This was impossible until someone counter bores the shaft hole to a larger diameter than the bottom of the splines. I also had to shorten the shaft by one quarter inch to make sure nothing would bind. CCP admitted they had made a bad batch of rag joint extensions but no compensation or corrected rag joint was offered.
I put the 400 box in my 69 nova and the steering was fine as long as the front tires were off the ground but when I lowered the car the steering got stiff and the wheel would not turn smooth. Then it started to steer on its own back the left. This is the second box from CPP, the first one was way worse as it would barely turn as all. I have a good ASE mechanic that did the install with me. HELP
