I was just looking for a steering wheel and I noticed a few things that were interchangeable. I believe the door handle system is the same, and the electric window controls too. Is there any compilation of interchangeable parts out there? I did not have an (LS?)300 to look at but it would be nice if it was the same steering wheel too. At least those were the nicer sewn leather wheels. But it would be nice to know if there were other manufacturers out there that might use the same wheel? Or more to the point, was the wheel made by a different manufacturer other than Toyota and sold to other companies?
