an Fbody radiator is a good cheep way to knock off a bunch of weight off the nose too.

My 95% complete front steel bumper was 55lbs, my fiberglass bumper is less then 4lbs, I didn't weigh the front steel support bumper shocks but I'm guessing less then 10lbs a piece, planing on aluminum one my self. They are said to be lighter.....

A full set of plastic headlights saves about 3 pounds vs. the stock glass ones.

How much weight difference is there between a car with power windows, locks and seats vs one with crank windows, no power locks, and manual seats?

just about done lighting up murphs T and thats down to just over 3000 lb car only

power seat setup adds 11lbs vs manual
power windows the regulator for power weighs 5.5lbs ea , the manual weighs 3.9lbs ea , so not much and then theres the wiring switches relay which might be about a little over a pound so going manual only looses about 3.5lbs ... he wanted to go manual but we kept the power because his cage A pillar bars running infront of dash got in the way of a manual crank
power lock solenoids are about 1 lb ea + wiring so maybe 3lbs

if you have a roll bar the crash bars inside the door can be removed which we did on murphs they weigh approx 12.5 lbs ea there went 25lbs , loose the rubber strip at door bottom thats 2lbs and loose the concert door speakers that was another 5

Weight savings:
yada yada yada

most of those weights listed must not have been done on a certified scale , much of what i read on that list is inaccurate , i could see a pound or two but some are off over 10lbs on the claims ..

the old saying 'your results may vary' definitely applies

So only around 17lb apx difference. Thought it would have been more than that. Mine has no power accessories, concert sound, export front bumper/aluminum rear, aluminum drums, and aluminum wheels. Never had it on a scale though.
