I have installed the adjustable front axle and disc brakes without a problem. Be sure to read “PinkMG” on the proceedure.
However the ball joints are another situation. I installed the Brazillion made and the German made with the same results, a very still steering that isn’t getting any better even though I have put about 2000 miles on the car since I installed the German made ball joints. The parts place and this Form has said with wear they will become looser.
I installed the “EMPI” style wheels also.
