Grade 8 bolts except the 2 at 10:00 and 2:00 which I install a little extra long studs to aid with installation...get the trans close and slide it up onto the studs..

I greatly respect Big Steve and know from experience that he builds high-quality race cars. However, I'm afraid I have to disagree with him. I rarely use lock washers [I do not like how they dig into the metal] As stated above, in my experience, the best options are a flanged head bolt or a standard bolt with a washer. Grade 5 is entirely acceptable. With an OE Powerglide case, the two lower bolts are slightly longer, so watch for full tread engagement in all positions.

guess odd man out. Like that new. I use studs.. IMO it makes lining everything up easier

Wide, studs are fine except in door cars with the original floor, where clearance would not allow them to do so.

1 1/2" iirc.

I use the Tractor Supply grade 8 hex head, no washer or lock washer.
O.E.M. never had a washer or flange on any transmission bolts, but I'm not at all opposed to the flange bolt idea.

Longer block dowels work well for a guide in most door cars.

I use grade 8 flanged bolts, then a high quality lock washer, then a flat washer with the rounded edge facing the transmission (so it doesn't damage the face of the transmission). This spreads the tension over a wider surface area. The transmission (the shear weight) doesn't rest on any part of the thread and no part of the threaded area enters the block.

Grade 5 or greater flanged bolt would be correct for this application.

I never use lock washer, To many times pulling old cars apart and seeing them broke in half.

Loctite or poly lock nuts on race cars.

I could go measure one that I have been using I guess, but again, if I remember correctly, it's 1.5"
