TBird 9 inch

[65Slickman]

I took the whole drive train from one of my 70 TBird parts cars and put the motor and trans in my 65.I was going to stay with the original rear end but have since decided to put the rear end in also and was wondering if anyone has done this and done away with the leaf springs and gone with coil overs.I don't think it would be to hard since it's a coil spring rear already.

What do you hope to gain by changing the entire rearend? Your truck probably already has a 9".

Changing to coils you would have to make coil mounts and shock mounts on the frame. You would also have to build mounts for the rear trailing arms or put a 4 bar setup in it.

If you are not looking to lower the truck a bunch, and don't mind building all the mounts and getting the geometry right, it can be done.

Yeah, what he said. Seems like a whole lot of extra work for really no gain. JMO.

A couple of reasons are it would be easier to go with a 4 link plus if the leaf springs are out of the way wider tires can be used with offset rims and also the bolt pattern is 5 on 4 1/2.I wouldn't have to make coil mounts if I use coil overs so all I will have to do is make the mounts for the 4 link.Just wondering if anyone has done this as I haven't seen any pictures of any.As for the gain there isn't much adjustment on the leaf springs and the truck will be for street strip use also never really been a fan of leaf springs.
