Belmetric.com also has a very selection of P.C. 10.9 hardware with those fine and extra fine threads for many of our suspension parts. They also have both nylock and all metal lock nuts in those sizes. Consider getting the lower shock bolts or at least the nuts as they often corrode or strip out. Make sure the top shock bumper still has the bushing in it and replace the top damper, (donut) if needed.

Subject: Bilstein shock tower nuts found

Thanks again to all who offered good advice for helping me resolve this issue. Turns out I was a nitwit in the hardware store and didn't double check the nuts I was using to size the shock tower threads. The said nuts had been mis-stocked, what I thought were M10 x 1.0 were in fact 1.25 threads. I shall be more thorough in future ( Ha! ). So I ordered some 10.9 strength ones from Bolt Depot ( thanks Jeff ) Rick
