J10 bench seat bolt size ?

[candymancan]

Floors are done and i want to put the ssat back in. But i never had the bolts as prior owmer removed it. What size are they ? My buckets of bolts in my shop.. none of them fit so im guessing now

3/8 fine thread. I believe its a stud with fine thread inside and course going into the floor. Are the welded nuts still in the floor. If not, any 3/8 will work fine

Yea the nuts are still there all of them for the bench seat and if i wanted two seats and a middle section. Seems the J10 came eith the option for either.

Some if the threaded sections are tapped direcfly into the floor supports not nuts themselves.

Thanks ill get some 3/8th. Fine tjread i am assuming you mean like say 3/8 24 or do you think lower ?

Maybe ill grab both course and fine. Can always use bolts for other things if i have extras

My Wag has 3/8-16 in the floor.

3/8th doesnt fit.. fine or course. Jist sits on top of thr holes.. all of them. I tried 5/16th and its slightly too small it threads but wiggles. And 3/8th is way too large.

This is frustrating as hell. If i csn find my tap set im just gonna drill and tap it to a size that will fit like 3/8th 16 lol

I drilled and tapped it to 3/8th. Now its all good.

I have NO idea what this 76 J10 bolts were from factory but g damn they were not 5/16 or 3/8th.
