Anyone know of a wheel specs database for OEM wheels?

I'm having a hell of a time finding a 16" rim for my snow tires, so I'm trying to find a more "common" model I can give them so I don't get the "I got nothing in 16" for your car" comment.

I've heard the 03-07 Accord is pretty much a fit for our car. Anyone find the specs on a factory wheel for them? Is it identical right down to the centerbore and offset? I've seen conflicting information for the Accord (one site said it had a 73mm centerbore and a 40 offset, while others say 64mm and a 50 offset)

I'm thinking of heading down to the local wrecking yards to find a set of steelies or factory alloys since nobody here seems to stock anything that fits.

Most places seem to stock a +40 offset wheel which seems to be quite a bit off from the factory specs. Anyone running a +40 offset on their wheels and have you had problems with that? I've heard that +45 to +55mm is the range we should stay in.
