Well where do I Start? STAY AWAY FROM THIS PLACE!! Well, not only do they sell defective parts but they will not stand behind their product and honor any kind of warranty..my husband bought parts for his 302 engine, mind he's a mechanic so he knows his parts and how things should work..he told them specifically what he wanted and they sold him defective product which cause damage to other parts of the engine he had to take it a part it was a mess..called them right away sent pictures and did everything they asked for and they said sorry we can't do nothing..so it's costed us double the money..thank God labor is free since he's doing the work..so if you want to save the grief don't buy from them..since the incident his shop pulled their account and will not buy from Junk Authority..Note I'm giving it one star because I can't give -100.
