big block A-body weight

my 68 barracuda coupe 383 4 speed Dana 60 wieghs 3042 lbs. All steel stripped interior no back seat. I have disc brakes all around and steel wheels out back with torque thrusts on the front. That is with a 1/2 tank of gas.
I have all glass except the rear, it is plexi.

This year I am going fiberglass fenders, 1 race seat, not 2 stock seats. I am ditching the stock fuel tank and installing a 4 gallon up front. I will see what the wieght difference will be.
