What length bolt for th350 crank spacer?
I bought a spacer to use a th350 on my 5.3 engine. I bought it from GM with the bolts they recommended. The problem is the bolts are the same length as the old ones that hold the flex plate on. I only have 1/4" of threads to hold the spacer. That is only 4 threads. There is no way I can tighten this without stripping the crank hub.
The spacer is 10mm thick so I would expect the new bolts to be almost 10mm longer.
The bolts I bought are 11mm 1.5pitch x 23mm long shoulder to end just like the original flex plate bolts..
I figure I need 30mm long or more to equal the holding strength of the original bolts.
Does anyone know what length bolt I need?
