Question on some rally wheels I picked up yesterday

[undr8ed]

After searching last night and this morning, I'm still lost (and since there's an abundance of knowledgeable people on here, figured I'd ask...)

Anybody know what these came off of or if a set of truck rally centers will work?

Rims: 5x5" pattern, 15" diameter, 7.5" width (inside lip to inside lip,) with a 2.5" backspace, inside nubs (on the centers) for the baby moons (only 2 of the bowtie ones and 5 of the plain,) and no open areas between the wheel center and outer "hoop"
