when we got our 71 Duster years ago(it's been sold), it weighed with driver 3300lbs...I thought that was really heavy since it had a light weight pin on hood, rear deck and the thin glass doors....

so what I did was...removed all the overweight thick walled roll cage...was out of date anyways and welded in a proper mild steel cage...

next I replaced all the glass with Lexan....any bracket that was removable and wasn't structural was replaced with aluminum..

the fuel cell was replace with a 10gal aluminum tanks versus the heavy plastic caved in tank...

at weigh in with my wife as driver, it was just under 2700lbs...

the 63 Dodge that I'm building, should come in at 2800lbs...the entire back half will be aluminum including the tubs...the cage will be molly tubing...the front half is boxed and will have an AlterKtion front assembly, the rear suspension is a 4-link using Molly tubes...Im keep the factory glass but will have Lexan roll ups...this will be a street/strip car
