Clutch Inspection Plate Bolt Sizes

[RhettS]

1986 CJ7 - AMC 258 i6 / 4.2l - T-5 for context. Just purchased this after looking at it this weekend and noticed the inspection plate on the lower bellhousing is missing. Picking it up this weekend and I’ve sourced a replacement plate, but have no idea on bolt sizes to attach it (they are missing as well). Any info from the experts here on size/pitch/length?

I'll check mine when I get home. I believe it's 4 - 1/4-20
