I need some bolts so I can bolt the TH350 gearbox to a 305ci Chevy lump, I was told previously that the size should be 7/16" unc, I bought them and they are too big, any ideas what ishould have? It might just be the thread size is wrong but I'm not sure.
Whilst I am at it what size do I need for the intake manifold? Standard manifold being fitted for the time being.
Thanks in advance to all.
