Haynes doesn't list this for soho but ey should be roughly same as ohv:
Mount insulator to frame nuts: 71 to 94 ft lbs
Mount insulator to bracket nuts: 65 to 85
Mount bracket to block: 45 to 60

As for tranny bolts. I don't worry too much about them. I remember 2 lengths (maybe three) and it's pretty intuitive about the lengths. Most of them are open back on the engine and can take any length. I think the top two are the only ones not open and require the bolt to not be too long. Just inspect the 8 motor holes and tranny holes and compare and contrast potential lengths.
