Im having trouble finding rims that fit the 99 bonneville does anybody have any idea where i could find any?

Have you checked the forsale section? There'* rims in there from time to time. Just do a search. I'll see what I can find for you.

I found soem doign a search for rims. But I dont know where your located. So it'* best for you to do it to save on shipping. Good luck.

Anything 7 1/2" wide and a 5 X 115mm bolt pattern will fit

That is a stock measurement on a 16'wheel

what kind of rims are you looking for? stock? aftermarket?
