I took these off the car last year and I've been racking my brain ever since trying to remember where they came off.


I put nuts back onto bolt and then put them into a ziploc bag. The shinny nuts fused to the bolt due to surface rust. I suspect the nut side is not exposed to the outside. It has 2 lock washers as well. Strong bolts, figured it's off the drive trane somewhere 5 each side??

Any ideas?

Torque converters ( I have 2). Bolt to ring gear?

hmmmmmmm
looks like 2 of em have different thickness of bolt heads ... and 6 are similar...

crossmember ? motor mount on the frame ?

I am an a body guy ... for whatever thats worth ..... doubblle lock washer is unique ,,,,

Those bolts are used on the trans crossmember and motor mounts.

what size are the bolts? with the head at 1/2" I would say they are 5/16". The crossmember and motor mounts were 3/8" bolts. If they are5/16" then more than likely they would be for the frontend sheetmetal

All bolts are the same size and come with nuts and lock washers.

3/8" bolt takes a 9/16ths wrench

I know that.
I just noticed the 0.5 and didn't take into account the 53 after it, and assumed it was 1/2". my bad

I took another look and 2 of the bolts are slightly smaller. Maybe it's the motor mounts on the frame.

Yes, I do believe your right, the bolts came off my engine to frame mounts and transmission crossmember to frame mounts.
