Welcome to CHR, Bob. The term "rat" carries a lot of different concepts, both good and bad. For me, the bad is the guys who pay no attention to safety and quality in their construction, throwing a bunch of crap together just for the shock value without any regard and laughing as they bounce down the road. When you can, post some pictures of your Olds, so we can see what you're doing, and your approach to what you call your "rat".
