Newbie 65 Dart suspension Question
Go for the 73 up disc brake set-up from any A-body (as mentioned).
This will give you the big bolt pattern. Plus brake parts are waaay cheaper than the earlier A-body brake parts.
For the rear,get an A-body 8 3/4. This is a small bolt rear,so you will have to get big bolt axles.
It will bolt right in. Be prepaired for a new drive shaft.
Here is a pic of my 65 vert,which has none of the above. lol
I kept the small bolt pattern,and used the 72 and earlier A-body Kelsey hayes brakes.
With the slant I kept the 7 1/4" and installed a 3.55 gear.
