Transmission Mount Bolts

Need to get some bolts to mount my transmission (th400). Anyone know what size bolts are required? This is for a 68 C10. Thanks.

Re: Transmission Mount Bolts

Trans to engine bell housing: 3/8 16 by 1 1/4" Use a 5/16" flat washer on the bolt and you won't have any slop in the bolt. Trans mount to the trans cross member will be 7/16 14 by 3/4 or 1". Grade 5 bolts are sufficient here.
