K-frame LCA stud "sleeve"

Get a piece of tubing to match to the od of the LCA stud and weld it in with a big flat washer on each side. The ID will pound out over time on a dirt car anyway. If you beef it with the washers at least it won't break out. They are not tapered to my knowledge. On my A-body dirt car I spent alot of time on the kmember, I did put new sleeves in the RF. Gusset the steering box mount as well. There is a circle track section on moparchat that would be of great help to you.

Also eliminate the lower rubber bump stop as this will bottom out and cause a push. I even notched the frame to give me a little more travel. F body Spindles lower the roll center plus give more camber as the rf pushes down. Use only Poly bushings as the rubber ones disappear quickly. Replace the strut rod bushing with a heim joint or I did it with a ball joint. Those bushings allow too much foreward and backward movement while braking and hard cornering. Just some thoughts. I built and raced an abody on dirt for 6 years and won quite a few trophies.
