Front end rebuild 1972 Duster
The inner shell/sleeve of the bushing needs to be supported from the back side as you press in the shaft.
Above you can see the rubber deform as the shaft gets pressed in. That doesn’t happen if you support the other end of the sleeve. I measured an old inner sleeve.
A 3/8” drive socket was the same diameter.
11/16” for reference.
With the socket in the torsion bar hex socket to support the inner sleeve…
No damage. The inner sleeve ended up where it should.
Now to better weld the stiffener plates, sand blasted and paint.
