Over the years, I bought two whole, new, 71/72 4x4 steering couplers that included the rag disc. One from LMC and one from GMCPauls. Both were the same repro part made in Taiwan. Both splined hubs on them needed to be spread to get them on the steering gear without destroying the splines or having to hammer on them and risk damaging the steering gear internals. Both seemed fine, otherwise.
Oh, both came with a coupler-to-steering-gear-shaft, hex headed retainer bolt instead of the GM style 12-point headed bolt. The 12-point bolt better allows a socket in the tight confines. I simply reused the original 12-point bolts.
Next time, I'll investigate what GM still offers. Last time I checked, just the rag disc thru a dealer cost more than a whole repro coupler. Hopefully, ya still get what ya pay for thru GM on this.
