"M" in the middle. I'm guessing these are originals. Or Marlin has been horsing around with my motor.

Paragon shows "M" bolts in their charts,##1799-1688-#4759-#626,but none that come close to resembling what you show.The declare them as Bumper bolts too.

Unless it's a "W"..still not in their charts.

Doesn't look like a "W" to me Mickey.

I already have a set of the "M" bumper bolts.

It sounds like noone would ever know if they are original or not anyway by the soundof this discussion

I agree. Guess we can put this thread to rest.

Darren, just went out to the shop to check out the head bolts on my 69 Z. They have ARP bolts. I couldn't remember what was stamped on the head bolts, since I last turned wrenches in the engine compartment a couple of months ago.

Well Darren,
I went out in the shop and got greasy last night. (sorry, no digital pictures). My original 7/16-14 SB head bolts are as follows:
Long: 14 per engine, 3 11/16", One raised circle 13/32" dia with 1 recessed circle 7/32" dia, with a "C" in the center
Med: 4 per engine: 2 7/8", same raised circle, no center recess, rasied "CP" in center
Short: 16 per engine: 1 3/4", same raised circle, no center recess, raised "U" in center. Also found more shortys with the same head as the Med. bolts.

After all that, Paragon's chart didn't even come close to any of them, markings OR lengths.
Sorry.

Verne
