TH350 Dust cover bolt size?

[Jonce]

Anybody know what size bolts are needed to hold the dust cover on?



I am putting a new GM crate and th350 tranny into my \'71 GMC and my dust cover didn\'t come with any hardware. I went from a 3 speed manual to an automatic.

dont remember but i think they are 1/4 20. i never use the covers due to the convertors i run and it helps keep the convertor cool along with the trans fluid.
