You are 100% correct on the number of people looking for information and not offering any. There are allot of very knowledgable people out there on this site that know a great deal but for whatever reason choose to remain silent. I know some members that tried sending direct emails to other members asking questions and never receive a response.
As your post here, "Bombardier Rims" goes to show. There were 20 views of the post, but when it was just information you were asking for, no one bothered trying to provide any help. If, on the other hand, you were selling bombardier rims, you would most likely be on your third page with inquires asking how much and how many you had.
If there is no one on this site that doesn't have a rim to measure, then they are in a shorter supply than I thought.
Those websites you gave us for possible suppliers for lights, door handles, wiper motors etc.. have been very useful to me. There's allot of intreseting products out there that may be useful to us for our machines, but we may never find the sites. It's nice when someone posts them for others to look at and maybe use.
