Review on 🔧 Belltech 4975 Pinion Shim Set: Precision-engineered for Optimal Gear Alignment and Performance by Kory Shelton

I used these to improve the gear angle on my 1972 AMC Javelin. The pins that came with it were too big to fit the holes in my nibs, but I was able to reuse the old pins. This probably wouldn't be possible with thicker pads, but class 2 pads are quite narrow. I had to make some spacers out of an old suspension bushing to allow the pin to protrude through the spring enough when the spacer is in place. There were some threaded hex spacers included in the kit but I have no idea what they are for as we don't have instructions and I haven't found them useful in my application.
