Friend that did the bodywork on my car refused to let me put glass fenders on it. They are a few pounds lighter, at best, and for the amount of work it takes for them to fit and be right they just are not worth the trouble, according to him. Assuming that you want the fit & finish to be beyond just acceptable (based on the way on your car looks now) I think you will be disappointed. I have a glass hood on my car and am seriously considered getting rid of it down the road if I don't need it, after hours of screwing with it it is still proud in the rear corner. Turbos like the load of high gears, but from what I understand blowers need lower gears.....is the 3.50 enough gear?
