Well...that thing looks pretty rusty. I mean, after sandblasting, it'll show a lot more eaten up than what you can see.
It'll take $50k to restore that car somewhat properly. So....figure...if it's #s matching, I'd say $25k. Not #s....maybe $22-24k. Again, for Mopars, #s matching isn't that big a deal if it's got other docs (VIN, original fender tag, rad support, cowl).
Thing is...it's a cool car, but not my cup of tea. I'd rather have a u-code four-speed.
