Transmission Bolts

Fasteners and Grade 8 Bolts, Oh My!

Let’s have a conversation about fasteners, specifically bolts for 4 speed transmissions, all of ’em, the ST10, Muncie trans of all flavors and Ford Toploaders.

I often see people advertising the use of grade 8 bolts on their manual transmissions.

I don’t think this is a good idea. In fact, I don’t know of any 4 speed transmissions in the 1960’s or 70s that used nor suggested a grade 8 bolt.
