Sorry, Greg, I don't have a photo, but I believe I can describe the front caliper attaching bolts such that you'll know one when you see it. It seems like the rear calipers have the same attaching bolt, but I can't confirm that from my records.

The front caliper attaching bolts are Grade 8, hex head, 7/16" NC thread X 1 1/4" long, with a black phosphate finish. Head markings are six radial lines, one at each hex "corner", with a small rectangular trapezoid parallel to one flat between two of the radial lines.

If you don't understand this description, I'll try to clarify. Exact reproductions were available once, but I haven't looked in awhile.

...If you don't understand this description, I'll try to clarify...

Here's a hand sketch...maybe this will help.

The headstamp of interest is the second one down on the form. (For those that may recogize it, the form used to record this headstamp sketch was developed by and borrowed from the late John Woods.) It's not obvious here, but the modified trapezoid mark on the head is like a tiny rectangle with the long sides and the ends "pushed in"...kind of like a stylized "dog bone".

Even though the headstamp directly below, or third headstamp down, has a big "L" and a little "5", it has nothing to do with the LS5 type engine. That is a common headstamp on early C3 Corvettes. On my 70, (edit ...the upper rear shock mounting bolts had that headmark: 7/16" NF thread by 2 1/8", black phosphate finish.
