k frame bolts
Thursday, April 03, 2014 4:00 AM
hey guys, can anyone tell me the size of the k frame bolts that bolt into the main frame of the car? i did an engine swap in my car and had it all apart and broke the heads off the bolts when taking them out. got them out and now i cant find the damn things. im pretty sure its a 1/2" by 4" long but i wanted to verify before going and buying new ones. also need to know the thread pitch.

Bolt # 13: Not Listed. GM P/N 22600725

Bolt #29: Not Listed. GM P/N 22583411

Bolt #34: Hex flanged head, M10x1.5mmx25mm, 22.30mm outside diameter head, header point, Grade 10.9

I actually believe the subframe bolts are 14mm, but I could be wrong.

Well the info I pulled was direct from GM, but I didn't find the actual rear two. They are not listed on any schematic I have access to.

If they are 14mm, GM normally uses 2.0mm thread for all 14mm bolts.
