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??
