My 1981 Avanti is getting closer to handling like my 1964. I removed the bellcrank bracket with shaft and cleaned it with solvent. It was still tight and rotated smoothly. When I removed the 7/16” - 20 x 2-1/4” pinch bolt , it was only snug. I doubt it even had 25 ft lbs of torque. The threads were buggered up, so I purchased a new replacement. When I got it all put back together, new zerk fitting, greased properly and torqued to 65 ft lbs and took it out for a test drive. I put nearly 70 miles on it today and the steering feels much better. It still doesn’t seem 100%, but I’m hoping that it just needs to be aligned to clear up the steering completely. But the excessive play was pretty much eliminated with the proper torque of the Bellcrank pinchbolt.
