I have a set of GTS covers on my SS and they fit great, and at one point i had a set of AVS covers for it and they fit like crap, now that im in the market for a set of covers for my Z28 and i haven purchased a set in like 3 years, has the quality changed? i seen on ebay they have a limited supply of GTS, but i see alot of LUND and AVS. is the fitment better now than it was?
