He isn't a bad dude...so, I am sure he will make it right, but you bought the things thinking it would work, so I don't see how he is the bad guy here. Hell I have bought things that didn't work, and ate them, then resold them. Just PM the guy, he isn't on here all the time... Knowledge about the parts first, then buy... I too think they will work car to car, but the experts would know more than me...
