As part of my AX weight loss program I removed the bumper "tits" off my 74 today. Thats a good 8-10 lbs gone. Pulled the rear heater fan and few other things too. ...and that firewall insulation mat is incredibly heavy! I'm easily up to 100 lbs + off the car now. The KH header and Supertrapp muffler really shed a ton of weight from the stock system.
Fibergalss decks and bumpers will be here soon too.
I'm starting the South Beach Diet this week as well and hope to lose 50 lbs.
By the end of the season I should easily be down 200 lbs (driver + car) from where I started just last month.
I'm definetly slipping down the slope to a dedicated AX car now.
