front suspension help
I have a 72 SWB with a hole rusted in one upper control arm. I already have a rebuild kit from pst and 2" drop spindles for a 72. I also have a complete 68 front suspension, a 70 parts truck, and a disk front end that came out of a 68 parts truck.
My two questions are; What is the same / different between the 68, 70, and 72 front ends? Any way to identify the disk front end out of the 68? |

Re: front suspension help
The main difference between your 72 upper control arms and the 68-70 upper control arms is the ball joints as the 71-72 upper ball joints are unique to those years. I have not done the ball joint swapout but the 71-72 upper ball joint should fit the older upper control arms.
As far as identifying what a PO installed into the 68 it would be anybody's guess as the whole cross member can be swapped in from newer trucks. Pictures may help but I would suggest matching up the parts with your 72 to see if they are the same. Jim

Re: front suspension help
I know the ball joint tapers differ.
I think the control arm bushings change. Does anyone know what changes are made on what years say from 67 - 87? |
