73+ K-frame build (pics)

Here is How I initially discovered the lower arm movement. Initially I had a red poly kit in my Duster. I replaced the poly strut bushings after they crumbled apart one weekend. I still had red lower poly bushings in the Duster. I had a weld leaking on the pan and I was looking for a oil leak at Numidia dragway.

I backed the car out of the race trailer and hit the brakes at the bottom of the ramp. started looking for the leak and saw the gap on the pin between the bushing and the K-member. We put the car in low with the brake on and they went back against. With a 5500 converter we were going from low to reverse and the bushing was backing off the pin and back on. After that we tore the control arms out and replaced them with factory bushings. They never move again.

They only back out when hitting the brakes in reverse. and go in when hitting the brakes going forward. Other members on this site saw this , Not only me. If your bars are in all the way it will hold them but if they move back the arm will too. I have a car that the bar come out due to no clip and then the arm came off of the pin.
