Oil Cap Restoration

[Mulsanne Blue]

Wow, new perspective, thanks. I’ve always thought these caps were rather elusive to find. Prior to posting, I did a Goggle searched and I remember seeing MerCruiser in the list. I just assumed they would supply only a functional replacement. Do you if theirs has the square configuration on the rivet bottom (the end that gets “smashed”, for lack of better terms), original profile, SM stamp, etc?
If you have one, please let me know.
I attached a couple pictures of the cap GM#3851735.
Thanks, Scott
