I looked at the 1985 SJ410 tranny I have and the bolt hole look to be the same size so one would think that the bolts are the same size. Anyone out there need an 85 SJ410 tranny in excellent condition???
Hmm, no PM. But I did find the bolts - 10x1.25 - needed two that were 100mm long to bolt my engine stand through to the block and then used two 3/8 inch bolts with nuts for the other two attachments to the stand.
