I just picked up four stainless steel (A2-70) M10x40, 1.5 thread bolts, four stainless M10 washers and four BMW copper M10 nuts. Oddly the nuts on there right now are not copper. They also use one size smaller socket than the BMW copper nuts I just picked up. Hmmmm.....
The stainless bolts were $1.69 each and the stainless washers were $.88 for four.
Hopefully the welds that hold the studs into the manifold will cut off easily with a Dremel cutoff. By the way, these studs don't seem to be pressed into the manifold flange like the 6 cylinder cars I'm reading about on bf.c. It's basically just a thin flange head then directly to the bolt/stud's threads.
Old sheared stud w/new bolt.
