Factory steel rim mix up, would someone kindly tell me which one is mine?

[72timemachine]

My landlord, who owns a '75 g20 van mixed up my steel rims with his. Mine were in storage and he started using mine when his wore out. No big deal but now there are two different 5 lug rim styles and it's been so long, I do not recall which ones are mine.

If you look at the valve stem or hole which attaches it, the center portion of the rim which is welded to the outer portion of the rim are flush with each other.

The other rim is different in that if you look at the valve stem once again, the center portion is set about a 1/2" or so deeper than the outer portion of the rim it is welded to. Both have the 4 bumps which hold the hubcaps on.

Would the rim which is flush on both the inner and outer be for a g20 van because the axle is wider than a c/10, 12 bolt rear end, or am I incorrect.

Thanks for any detective work, I do appreciate it.
