the right offset??

[Eurolook71]

I Really like these rims, but the only offset offered was 38MM. They are 16X7s, and would be going on a 71' super, with Maxx struts. I'm going to have flared fenders and was wondering if this offset would be ok. I really don't wont to use spacers, but will to get the right look, (but nothing to thick!).

Also, I keep getting confussed with offsets...

the higher the number, the closer to the strut (or inner fender) and the lower the number, the more it will stick out, right????
