I purchased 3 b body complete stm. 2 years ago at Carlile from Don but I think he's the grandson not jr. Had no issues paid for them he had some parts there pick up the rest of the part this year some trust involved but all was good. My Budy did the same but felt the need to call him in between never call him back not good business but had every at Carlile this year. I have installed one set fit very nice tips hanger's tailpipe h pipe 68 440 gtx.
