Con Rod Part #
 

Need application for GM PN 1476521 (# on the box). Supposed to be HP 302 rods. I imagine this is a superceded #, but I don't have any reference sources for the part.

If you carefully remove that top sticker, you should be able to see the original number on the one below. It might give us more info...

Good call, Ed https://www.yenko.net/ubbthreads/imag...ns/scholar.gif. The sticker came off easily - shows 3963552 and in the blacked over area - 3969804.
