Spriso Motorsports Billet Aluminum Datsun 510 Differential Moustache Bar

All one piece 6061 aluminum, CNC'd from a single piece. Eric Straw did a fantastic job of getting these made. Stock steel moustache bar w/ bushings weighs 4.18lbs. This aluminum bar w/ bushings weighs 2.22lbs. Uses TMC part # CIN-245 240z polyurethane bushings which are a tight press fit. Too bad the spare tire well blocks it from view unless the car is up on a lift.
