There's lots of questions about what you can and can't do with your car regarding
keeping your warrantee... Does anyone have access to a copy of the Warrantee act... think it came out in about 1974 to clear up some of these questions and establishes minimum limits for manufactures. My buddy who is the sales mgr at our local dealership say't that the dealers are the ones who are in a sticky spot when they refuse warranty due to unrelated modifications...

This could be just for Canada but I am pretty sure it's the NORTH AMERICAN act, so it covers the U.S. as well...
