Well last night i started putting my car back together and now i cant find some bolts. So i was wondering if anyone knows what type(s) of bolts are used to bolt the j-pipe on the block. I'm also wondering about the bolts that hold the crossmember on the chassis. like the length and size thanks

this might help, 91 fwd tsi

uhh, please explain the J pipe your talking about. and there should be 2 cross members. is it the one on the drivers side or passenger side. front or back.

what i was talking about was the oil return line, which i got those bolts. the only ones i need now are the f+b crossmember bolts, 3 of them that sit right under the floor board. they screw directly into the chassis. i think they're like a 16,17, or 18mm, but at a buck a piece at farm+fleet i just get sick of buying the wrong size
