Hey guys, I'm wanting to know what if any differences there are between the '64 f100 and f250 straight axle spindles. I'm wanting to do the disk brake conversion that FarmMotorSports did. and yes I'm fully aware that the kits would be much simpler but by doing it like farmmotorsports did I use all ford parts, and the calipers are newer than the gm calipers in the kits I think the kits said 70s gm calipers and the ones you use with farmmotoresports conversion are 01-07 if I'm not mistaken. So Im hoping my f100 spindles are the same or close so that I can make a bracket and not have to mess with swapping spindles...although I'll probably end up getting or borrowing a set to mach up my parts as I'm driving my 64 daily now back and fourth to hs and this is my senior year so I'm wanting to get most of this knocked out before I go to collage.

My plan is to get power disk brakes all the way around, get a sway bar up front and rear one later, whats the best one to use that I don't use the shady brackets ive seen people use.
A coil spring helper shock add on kit on the front shocks if they are not to big around to clear the shock brackets :lol:.

Right now I have the ram power assist kit, and I'm going to get the control valve rebuilt as it quit right before it got tagged again. and my dad installed wedges to make it drive straight and it handles great with little play but we both feel like it needs a bit more wedge as above 60 mph it starts to feel a bit loose and gets worse from there. It does have fresh kingpins and tie rods. I need to replace the leaf springs up front as mine have some pretty serious wear on the ends where the leafs rubbed in they're 53 years of service...who has the most affordable and best handling leafs? I'm getting side tracked :lol: but these are all things I'm needing information on that I'm having trouble finding. I'll be sure to get some pics posted of the set up before we took the power assist off.
As always thanks in advanced.

Also what kind of steel should I use to make the brackets out of? I have access to a machine shop as I got to a vo-tech school sort of thing in the mornings so I have acess to lathes, mills ,and a CNC mill and lathe once I learn the programming.

I'm assuming we're talking about this thread: viewtopic.php?f=1&t=37265&p=307764#p307764

I would actually recommend you determine the significant differences between the F-100 and F-250 hubs, and find out if you could simply bolt a rotor to the back of your existing hub in similar fashion. Also, I don't see any reason one couldn't use the same rotors and bearings as the Speedway/CPP kits, source a Ford caliper, and make custom brackets (which it sounds like you'd do anyway) if you're opposed to using GM stuff.

The spindles are the same. I parted out a 64 F250 and transferred the springs, rear axle and all the brakes over to my 64 F100. Front hubs even use the same wheel bearings, only difference being 8 lug instead of 5. Hope this helps.

F100 Vs F250 spindles - they are the same...
Mounting plate, I personally prefer 3/8" plate, I will tow, and haul more than I should. I want the failure to be on a part I didn't make.
Some of those kits you spoke of, use 1/4" plate and only 3 of the four possible mount points on the spindle.

In the end it's up to you to make it as safe as possible, your off the map, building your own brake system.

My formula was:
Rotor selection the largest vented rotor I could have with the correct bolt pattern and mount style.
Caliper with bracket selection caliper must fit the rotor of choice for thickness and diameter. And must have a factory floating bracket assembly that unbolts from the original spindle.
Adapter fabrication once you have the rotor on and caliper mocked in position on the rotor, you can see what you need to fab between your spindle and the floating bracket...

I have not done it, but have been told that you can swap the spindles from the dentsides (73-79) onto your straight axle. You'd have to make sure the kingpins were the same diameter, and may need some spacers. Hopefully someone on here has done this and will speak up.

Ya that would make things simpler if I could just use the dentside spindles and have easy bolt on ford calipers...That's interesting ya hopefully someone will speak up if they will interchange I'd love to learn more about that without buying a bunch of spindles to play with. That also would give me kingpin dust caps instead of the rubber o rings right? Good rubber is hard to find I already need one...cracked and fell off after 2 years..sitting..

What type Metal should I use...what did you use? And you wouldn't happen to have the specific measurements of your brackets would you? Maybe even the bolt pattern? ya I definently want to use slotted and drilled calipers If I can afford it...of course all that can be bought later as long as I get good used ones...but that's still risking having to have the rotor turned if its warped... But yes I'm currently running 16 inch rims...225/60s, I'll have to measure my spare later today.

I used plain steel 3/8" thick mild steel.
I have a cardboard template of my brackets. I'll bring you one to SS.
But the odds of a half ton disk having the same outer diameter and the caliper you chose having the same offset and bracket bolt pattern is almost 0


Outside rotor diameter was 12.5", any smaller than that my bracket will be wrong.
3.23 inch offset toward king pin from back of hub.
And then finding a 1/2 ton ford caliper to match my bracket bolt pattern...

I spent hours on O'Reilly's web site they offer detailed spec's on most parts. I tried several diferent vehicles looking at rotor Spec's checking, hub diameter, outer diameter, bolt pattern, thickness, offset etc. Then changed vehicles to the ones I thought would be good caliper/bracket donors and checked their spec's and compared the spec's of the matching rotors to what I wanted to use. If you haven't noticed my rotors are early 80's to get the 8 on 6.5" pattern and my calipers are 2000 and up metric patterns to get the calipers with bolt on floating bracket, instead of a bracket that is part of a spindle.

PS. O'Reilly's lists a 1972 king pin set as .8592 diameter...they don't list a 61 what's a 61-64 king pin size?

Ok, thanks. so I guess I'll pick up a 90s f150 rotor and caliper , hub assembly,a f250 caliper , and a 64 f100 spindle and see which one will be easier...how ever the f250s will be newer, but I'll still obviously have to make the bracket different to compensate. but as far as slick stock I'll have graduated by then... but ya if someone can speak up on the 61-64 spindle diameter That would be great, the only issue I fore see with just using 76 spindles if they fit is that Im not sure where the pitman arm/and or gear box location is is on an f250...I know the f150 would be tough but I saw an '76 f250 spindle the other night and the pitman arm looked Identical how ever it was in front of the spindle instead of behind like 61-64..

According to the info on Nostalgia Sid's site the 61-64 kingpin diameter is 0.859":

Interested in how you are going to rectify the spindle steering arm positions if you intend to use later spindles????
