Identify Steel Wheels

[Husk Challenger]

Hey guys,

I've just picked up steel wheels and i'd like to know the correct width...But i have tires on it.

I have 5 wheels but two differents width.

The first one i think it's 5.5" width because of the marks near the valve (5.5)

But for the other one i don't have this marks. I tried to measure but with the tire it's not really accurate... maybe 6"
I found a sort of serial number (3590361) and markings (M  31)  at the middle of the wheel. Any website to decode this?

Thanks and i hope it isn't too much confused.

Doesn't look like a 70 or 71 number.  maybe 72 or up?

Thanks cody

I have no idea from what car they come from.
May it be sooner than 70's also?

can't find the 3580361 - the center is from '72, the assembly is from '73 - is it 14"?  what else is stamped by the valve stem?

Wow that's impressive....

Both types of wheels are 15"
I will take better pics for the other marks

Thank you @6bblgt

Here are the pics @6bblgt

the  second wheel was assembled 1/30/73 with a late-72 dated center

there are a lot of #35800xx passenger car wheels that vintage, guessing it is originally from a van or pick-up
