Is there any (e-site) place I can find a "matrix" (to enter wheel specs.) that can tell me what car models a certain wheel was produced to fit? (ie: Brock, B1, 10Jx17 H2, ET20, 5x4.5). I bought several different wheels (as a lot) at an auction and now I need to know what these wheels could fit??????

not sure about a database, but there are only about a dozen common bolt patterns on the market. I'm away from my computer so I can't find the links, but I did a search for "wheel bolt pattern reference" or something like that and came up with two excellent pages. They just list the sizes and what they fit.
