Slot Mag Sizes and other Errata

I am looking for 2-13x4, 5 or 6" 4 on 4.5 BC. I have 2-13x5 4 on 4.25 to trade or sell. Thanks Gene

Oh yeah, what's the bolt pattern ???

 

I picked up some aluminum 15x14 Bart Wheels (which are also extremely lightweight) to match those 15x3.75 Bart's I already had



And some 15x4.5 U.S. Indy

 

Couple days ago I picked up these 15 x 3 3/4 unilug, like an E.T. but no name on them, they have 1 1/8 backspace, just an odd size and backspace.
