Thanks for all the replies guys. OK, here goes:
I think I will talk to the guy and pull some select stuff off of there, I don't have a clear idea of what his intent with the truck is anyway, originally he just wanted the frame?
Yeah, the seats are (I think) van seats from the same approx. year range, so they're not original, but they are in real good shape and I hope to have 4 buckets in the yellow one eventually (especially if I could figure out shoulder belt mounts for the rear)
I do have the bench and brackets, maybe I should pull those, that'd make two sets if I go buckets in the yellow.
No tilt or tach, but the AC system is good (and ac dash obviously)
The top is kind of jacked up (couple of cracks and the hatch latch is toast) but it is a double (I think, bolts mounted from top of rail, two lights) plus I have the top from the yellow one (which is single wall unless I have them backwards)
ANy other parts on there that are worth anything big (relatively)? I already took the two hooks off after seeing some posts here, holy crap those things are pricey!
As far as the engine goes, just a '74 truck engine, nothing special. I had thought about building it up a little and putting in the yellow one, but checked the yellow and it has a decent '69 high output motor that mortec says was orig. 300 HP
so that's probably the better builder.
As far as the trailer, I don't know, I'm gonna try and look at it this week, the plan is to lift it and paint it to match when I do the yellow one, probably with a pop-up style camper too.
At least this decision will help me get off the "Restore one and Wheel one" plan that'll never happen. No reason I can't make the yellow one look good and still wheel it.
