I see CARS has offered a rear wing for the 70-72 GSX, are there bracket or hardware needed to do a good install?
Does anyone know of the best rear spoiler to buy, I see CARS and The Parts Pace have them and read there are some differences, like one is flat across the and one has a slight curve to follow the body lines.
Well, part of the research you need to resolve is the fact that while there are more than one company making the rear spoilers, there are far more retailers selling them than the number of manufacturers. This means that many of the retailers are getting spoilers from the same manufacturers which, in turn, means that there are some retailers selling the same spoilers and other retailers selling different spoilers. Just so you're "in the know". If you're able to find the manufacturer of the spoiler you like/want, then follow that manufacturer downstream to a retailer of that spoiler. There are threads here discussing "issues" with certain spoilers fitment, finish quality, etc. And, there are originals which pop-up from time to time, though thry are pricey.
My only interaction with The Parts Place was NOT very good. Spoiler had been broken ( cracked on end) before they primed it. And TPP wanted ME to pay shipping effectively three times (original; return; replacement for THEIR problem... Hardware was various different sizes, gaskets were WAY too small. Bottom contours required a good bit of build-up to fit. Spoiler itself wasn't that bad after repairs to end and pedestal fitment. NEVER AGAIN!!!
