I have supported the TT store and vendors here with my pipe and carb ,but I am looking to go big bore and money is tighter now. Has anyone had problems getting parts on Ebay even though they are sometimes only listed for the LTZ and so on? I am aware of counterfits for the import car market but, does that exist here? I am looking for Hot Cams, CW BBK, Trailtech flywheel, and some repair parts. Would you guys advise against saving a few bucks and ordering it off Ebay inspite of saving 100 bucks all together?

do your homework before buying on ebay.i have bought lots of stuff(BB kit,sprokets,etc)and havent had to many problems.the only problems ive had were either the i got shipped the wrong product or the product never arrived.both problems were rectified

eBay is hit-and-miss. You just have to know the specifics of what you're seeking, and ask the necessary questions.
