I gutted mine but they're still damn heavy and I use the strap to keep the dr. door window up and the pass is fixed in the upper position.......I regret no keeping the window mechanisms now...........

I doubt that your doors have the dreaded crash beams that Drag racers hate and love to remove, but just about the only thing that can be of significant weight loss on stock doors is the CAREFUL drilling of dead zones in the inner metal skin or milling out of existing access holes on the inner skin. Also some material can be removed from the regulator window crank arms.This will take off more or less about 2-4 Lbs each door. Lightweight fasteners where ever safely possible.
One can chemically mill the whole door as well for more savings, but if they are to function like stock, I'm afraid one can't mill too much off to be worth the expense. Personally, If the doors were for my car, I would chemically mill even if it was only 10%-20% off.

Later this evening I'll post up Palm Readers meticulous drill out of his 68' doors that look stock even if they are hidden from the eye with the inner door panels. It wasn't much, but it all adds up.

Guilty as charged.

I have plenty of junk on the shelf that was bought, installed, used briefly or not at all, removed for some vague reason and put on the shelf. Or worse, I bought something, never even install said trinket but somehow it still wound up on the shelf.

Ditto,,,,happy holidays everyone!

I have refill the propane bottles,then I can pull the steering column and remove all the manual shifter remains and add a removable steering wheel.
Then I will attack the the column support,remove the clutch pedal and return spring.Have some "pretty" work to do also.
Just start chippin away at the winter upgrades.In the spring get right out for some great new best timez & mph-es

Tis the season.
If it were not for seasons, especially Winter, Fashion wouldn't exist nor weight removal programs for humans and cars. LOL.

Here's the Palm Readers lightened inner door on his 68' Coronet.
Lots of care and patience went into making all the holes and trimming to present a stock look. Note the carefully hole sawed window crank bridge behind the door skin.
This can be done to almost any door with care being considered to where the regulators are and the ability to function as the factory intended them to do so. My previous lightened doors have a crude version of this method to them and yet all the windows, vent wings and latches work as stock.

Close up of the window crank bridge arm.
Mind you, I advised him on the lightweight fasteners to hold it all together as far as non crucial items are concerned, but he was a stickler for stock bolts even if they are hidden. Really? LOL.

On another note, because he intends on showing this car as well as giving it a few trips down the track at some F.A.S.T events, here's a close up on the underneath of the fender apron vertical support which has been tastefully hole sawed and trimmed to suit.

Trust me fellas, this car is going to be a show stopper. More to come over this Winter. We're really looking forward to springing out this coming Spring.
Right now for some reason, I wish I had a new Demon to go to town with some light weight tricks being that it screams out oooohhhhhhhhh beastly.

Note to self: learn from Thumper's lesson .

FMJ - you are not helping my case for keeping the stock gutted doors in favor of a set of fiberglass replacements... I appreciate the sample pics! They give me a great reference point. I accept your challenge to find more than 4 lbs per door I will need to be careful this year as I haven't budgeted paint into the plan so I will be working on my metalsurgical skills

Glass doors will need a lot of work to make presentable and looking stock being that the window glass itself has to be set in the locked position. Many have regretted that decision on a street car.
There's nothing like a stock door on a street car that has been tricked out. Only you know the secrets. People can call out a fiberglass door from a mile away. On a race car I can see the reasoning, but on a street/strip combo, steel in any gauge is the way to go.
Those Dusters have been down to 2900 Lbs with all steel parts for the most part.

Agreed. This one is at 2965 without me. The class I run requires a functioning window adjacent to the driver so I'm planning to keep the window regulator. With the small block weight break the minimum weight is 2900 with driver. I'm hoping to find 100lbs hiding forward of the rear seat but am prepared to throw a lithium battery in the trunk if need be to get there.

That 2965 is a great starting point already. Gee, you don't have much more to go.
Lithium 20 pounder along with HD aluminum strand battery cable to the front. You'll be 65-75 Lbs away from your goal.

Is it legal to use a 2" nylon strap to lift and lower the window? A snap and the top and bottom of the door panel to fasten the strap.

I'm all about trimming weight, but I installed a power passenger window in my Dakota, I couldn't reach the window crank strapped in....Love the cool breeze in the staging lanes.

I'd bet that electric window regulators probably weigh less than the OE crank type.

When I was working at a dealership, I used to replace window regulators all the time. The mechanisms themselves are mostly plastic and thin cable with a little motor. Some of the more recent ones are like a full door panel but the previous iterations were pretty simple.

There are general 'street rod' electric window kits a available. Not sure how you'd retrofit something like that into our cars though, probably more work than it's worth.

I'm planning to lose 15 - 20lbs this winter myself. Most of that will probably come off by staying away from late night vodkas :}

dvw - I believe straps are allowed. The rules state the window "must operate in the OEM fashion - IE: go up and down". I like the idea of the strap or even power assist as it can be a PITA to roll up and down once strapped in. I'm going to check both options. I am a little concerned about power as it might lead to wanting more creature comforts like A/C!

I wish I would of gone this route here..........SUPER clean and bad azz...........

It does weigh less, I bought one for the driver's side, it's going in this winter.
