I have up for sale a shaftmasters 4 inch 1 piece aluminum driveshaft, with pinion adaptor. Works perfect, zero vibration. The only reason I am selling is because I went to a Magnum XL 6 speed, and had to have another shaft. This is one of the best mods I ever did to my car. Shaft is in perfect condition, just scratches from being installed and removed. $400 firm, plus the ride.
