I would trade both mine for my old Z28 back and it was a 13 second car....lol. It's just s car thing. I like my cars, I like the mods I have done. I still run stock exhausts as like that 'sleeper' kind of thing. Keep trying Jerry at Eurocharged. They work other jobs, and do quite a bit of traveling. So just keep after them. They do know that part of the car better than anyone. You may need to a road trip to Houston...lol. I hope to have my rear end mod done by the end of month first of October. That may be my last mod....
