satellite ('66)

Looks like most of the work could be bolt-ons from a 4D parts car.

Quarter patches have been made in the past but be careful as there are 2 versions, one MUCH better than the other.
The bad one is obviously flatter then the decent one.

Look at the frame right in back of the front shock area, all the way to and including the trans cross member.

Look around the joint between the c pillar and the roof.
That's a difficult repair.

Besides the wheel arch, those are the worst, most common rust prone areas on a 66/67 non Charger B.

Trunk, quarter extensions, dutchman are secondary areas.

I've also seen the rear frame rail near the shackle area go but this is not real common.

Floor pan (except trunk floor), frame rails, suspension and most of the uni-body is the same as 68/69 and some as 70 so those parts are readily available repro

Do you know the engine and options?
A G code 383 4 barrel is kind of rare. AC is kind of rare.

66/67 B's get the crap knocked out of them on the front corners.
Good fenders and chrome is somewhat pricey but can be found.

How did that hood survive unscathed?

How long has it been sitting without a windshield?

One of the more expensive things is the gas cap. $300 is normal...and it's a high theft item.
Cheaper (and more secure) to put on a 67 GTX flip cap.

I LOVE white with a blue interior on a 66/67 body.

If what we can't see is as good as what we can, I think you can do this for under 10K (excluding paint) if you shop wisely.
