What's my Demon worth?

I'm throwing out a feeler for my 71 Demon.



It's GF3 Light Green Metallic. Originally a slant six/column auto car, but now it has a 1998 5.9L Magnum engine, 904 transmission with floor shift (no console, just the mechanism).

It has no trunk floor but has galvanized steel riveted into place instead (it's waiting for a new 1-piece trunk floor), has some pretty good body damage to the tail panel, which should necessitate another tail panel put in.

Upgrades include custom dash panel:



Wilwood manual disc brakes:



Completely repainted and re-wired engine bay:





It also has hood pins and some other minor changes. Otherwise, its pretty much all there (or I have the extra parts sitting in the garage) and the rest of the body's in good shape. Most importantly, it runs and drives fine, even with the little 7.25" axle in the rear.

So if someone could help me identify what I could get for it, I'd be very appreciative. Thanks in advance.
