Wow that is so weird, I just bought a set of 4 very similar old AR wheels, 2 piece welded billet wheels
2 are 17x9 and two are 17x11
The two 17x9 were welded on by some idiot and they are going to be repairable, but very expensive to fix. The two 17x11 are great. I wish I could find replacements for the two 17x9s for my set so I don't have to spend $500 to fix them
My wheels have similar #s on the inside. They do not seem to correspond to any part # I can identify
Good luck
PS the wheels you have are NOT Lemans wheels.
This is an American Racing LeMans wheel (well known vintage wheel)
