[general statements]
I certainly wouldnt use them without seeing them in person first, no... and the chance of them being too stiff or too weak as a generic type would be pretty good, or having one blow out and create a massive mess. For 30 bucks, is it worth the risk and hassle- not to mention undercutting the people who support the club with a likely inferior product, for peanuts really.
The list price is 88 bucks a pair, as pointed out above, the cost is 70.40 after VCA Discount. Myself or Chuck can ship anyone out a set if need be. Easy Install. They generally get soft and take more force to lift up, but if you have a hatch that doesnt always stay up, you are certainly due. Considering the mess they make if they leak, preventative maintenance is pretty cheap insurance here.
I have gotta be honest with you guys on this one... seeing as an oil change costs more than these as a pair, what is the big deal on replacing them once every 5 years as general maintenance? A tank of gas or an oil change is right up there with this one- we arent talking about a 5000.00 item here.
