I have a 2000 CV 8.8 in my 64, it has 4.5 bolt circle. You could never get the wheels on it if you used wheel adaptors, it's squeeze getting my Bullit wheels on without jacking up the frame.
The brakes are great though.

I think this is the PERFECT FIT

Post by TXSlick »

I used a 2008 Crown Vic front end. Even the steering shaft was perfect length for my van tilt column.

For the rear end, a 1981-1983 F-100 9" is 66" flange to flange and has 31 spline axles. Sound too wide? I used 2002 Mustang 17x8 front wheels that have 5.72" backspacing. They fit perfectly under the front fenders. My truck will be lowered so that is important to me. In the back, I used 18x9 wheels with 6" backspacing. The remarkable result was the front (225x55/17 tire on 8") is exactly the same overall width as the rear (235x55/18 tire on 9") The rears fit perfectly under the quarter panel like they are supposed to.

I did have to relocate the spring perches on the rear axle, but the shock mounts actually lined up better than the original 66 mounts did. I found it easiest to just grind off the welds and trash the spring perches in the process because new perches are only $15 a pair from Jeg's.

i have a couple of truck tilt columns but i think they are a different length than the van tilt column. i think i remember Hawkrod stating that the van column are only good for parts for the truck columns so are not interchangeable. i will find one for a van however. i am going with the 73-79 rearend with the same width as yours. i have installed the DJM lowering shackles and front rear spring brackets but am not sure if it is going to be low enough. this weekend i am going to mock up the FE engine and C6 transmission again to make sure of the rearend pinion angle before spot welding the spring perches on the rearend. i also have removed several of the leaves off the rear leaf springs but am considering putting them back on prior to welding the spring perches on. How did you accomplish the lowering of your rearend to match the front? thanks.

also i found a local guy who specializes in building race converters and setting up rearends. he is going to redrill my axles and brake drums for the 4 1/2 inch bolt pattern and has done it many times and the price is right. only $75.

i have a pair of axles and rear brake drums being redrilled for the 4 1/2 inch bolt pattern. i called oreillys and tried to find a pair of brake drums with the 4 1/2 ich bolt pattern but they are for 10 inch brakes. it figures . lite duty axles. lite duty brakes but i thought i might get luck and be able to buy new brake drums with the correct bolt pattern. i got the angle set on the housing and tack welded in in place after mocking up an FE engine again and installing the driveshaft. now i pulled the rearend out again to finish welding the hangers and finsh removing the old shock mounts etc. next is reinstall the housing and figure out the shock placement with new rearend shock brackets. also i may have removed to many leaf spring leaves and i might add 1 or 2 more back in. my question now, with a lowered truck is the gas tank relocation to the rear going to be a problem? is there a problem with using a sport bumper and brackets after the relocation of the tank? thanks.

Jim, what diameter and width drums do you need?
They should be readily available, but if your old ones are good, redrilling is fine until replacement is needed.

Jim, have you considered using a disc brake setup such as this: http://www.speedwaymotors.com/9-Inch-Fo ... ,5336.html
Really not too bad considering...$349 w/o emergency brake and $429 with. Would give you a 11 1/4" rotor.

my goal is to get this truck running and driving with outside parts at a minimum. i am going to go pickup a set of mustang rims this afternoon and back to work on the frame tomrrow. when i get it running, i might find it necessary to upgrade the brakes and make other minor changes but the drivetrain stuff i already have just waiting for the right project and this is it. i will drive this truck to slickstock in kansas city this august. it might not be painted but i will have legal insurance and an antique tag. i have to keep busy on this thing and not waiting on parts to accomplish the goal. see you there. i am thinking about the mustang bench/bucket seat with the extended seat and bucket seat brackets for the interior and automatic on the floor. i have the correct c6 with the correct floor shift linkage and the mustang floor shifter and the right rod and everything to make it work so it should be a simple bolt on deal with very little modification. around here it is the good body parts that is the hard part to get. i may cannibalize other trucks i have in order to get a good body.

this time i am going with the 73 f100 31 spline axle, but the next time i will do the cv front and rear ends. the cv rears are cheap and plentiful around here. how about the emergency brake cable hookup? was it a PITA? i had the rearend out several times yesterday getting the lower shock brackets in the right postion. going to orielly's this am to see if i can't get some shorter shocks. next weekend going to set the engine transmission on the frame. going by ford dealer this am also to get new rubber bushings for the lower control arms. i guess that is what they are called. the part that bolts up to the frame behind crown vic cross member and just in front of the original mounts for the radius arms. thanks.

Do you have and if so can you post pictures of the CV rear under the truck. I'm interested in seeing how the tire/wheel fits under the fender. Everything I've read and seen indicates that the CV rear is WAY to wide for the Slick beds.

Grits,
I believe you have to use the 93 C V rear to get a good fit.

That's what I was thinking. Maybe I misread what oldfordcoupe wrote, but I read it that he used the front and rear out of the same vehicle, i.e. post 2003 CV.

i did put the cv rear in my 65 with the cop wheels . just to be sure i trimed about 1/4 in on the wheel well lip . so with the same size tires as the cop car the wheels an tires fix with the orig. springs there is no left or right movement of the rear end . like i said before it drives like a sports car + its a lot of fun when your behind these kids in there little jap cars an you stay right with them

now i have the axles and brake drums back from the machine shop. today we moved the sway bar back to the appropriate 5 1/4 inch measurement from the 4 front end mounting pins . this afternoon the POR 15 went on . i have a little more welding to do and tomorrow we are going to work on the mustang gas tank installation and some welding for the sport custom bumper brackets. i think the 73 to 79 rearend is about the right width if using modern wheels with the newer backspacing. i think the mustang wheels will leave the rear tire outside to outside measurement about 72 inches. then the engine /transmission are going in. machine shop did a super job. stabbing the newly machined axles with the 4 1/2 inch bolt pattern is tomorrow i hope. the whole project has been a piece of cake. so much so that i am going to pick up another crown vic front suspension tomorrow early am.

QUESTIONS:
FOR SLICKCOLLECTOR did you use the CV FRONT original 4 mount bolts? Doesn't look like it, what is the size DIA & length bolts and TYPE thread did you use, my CV being shipped to me may not have hardware

FOR oldfordcoupe, you said you used SAME CV front & rear SAME year with SAME COP WHEELS, I am considering same DO YOU HAVE PICTURES? Would love to see HOW yours look from side & REAR view, and clearance of rear wheels along with HOW you tied the rear ax in
THANKS GUYS!
