I know the washers that guy gave me compressed, and that he said he had the same ones on his car. I know this. I know a couple guys that would buy 16 4 cent washers over 16 7 cent washers, or a 50 cent bolt over the 80 bolt. I don't know the extact prices, but I know the cheap people that would buy the wrong ones not understanding there is a differenance. IMO they shouldn't be working on their cars either, due to the poor jerry rigging I've seen on a couple of them, it scaried me to think I could be driving next to them on the road.
If I didn't know these cheap asses I would be on your side of this arguement, but I do know a couple.
