I'm rebuilding the suspension on my 74 Lesabre. Somewhere along the way I misplaced the nuts and bolts for one of the upper control arms. Anyone happen to know what size those were? If I don't find them soon I'm going to get new ones.
Those are special bolts and nuts, you can't just replace them with regular hardware. Try Todd, http://www.diecastmusclecars.com/dcmbuickfasteners.htm
So you don't think grade 8 replacements would work? The only thing special I saw was the bolts were knurled at the base to keep them in place.
Exactly, that knurling is not optional, you need that. And the nuts are self locking. Get the right ones.
Well then yours are wrong. I provided you with a link to ToddsGS' website. http://www.diecastmusclecars.com/dcmbuickfasteners.htm If you scroll down, you'll see them in a kit. PM Todd and see if you can buy them separately.
