gm outsourcing parts

[frankv11]

I went to my local chevy dealership ( george chevrolet ) order a slave cylinder for 2001 camaro . after removing old one I notice it was completely different so I tried to return it next day ( intact , never installed ) the parts guy steve refuse to get my money back even thought I had receipt in hand. allegedly because it was not in a box . I explained to him and he recalled he kept box day before but still would not accept it, even though it was just a plain brown box no Pn , logo.. F it
well I went home installed it. figured gm sold it it should be good. few days later during normal use it busted, well after towing charges and more fun removing t56 on my drive way again..upon removal I saw that center part of throw out baring popped through center section of pressure plate.
I than went to my local O'reilley's auto parts and to my surprise , they're part ( slave cylinder ) is the same one as gm , skf made in argentina only difference is the price $60.00 @ O'reilley's $180.00 at dealership.
WTF ??
skf contact point of throw out baring to teeth of the pressure plate is stamp shaped metal in comparison with OG which was a two piece part , not stamped
ill see if I can upload a picture

really WTF!!!!!!
