Crew Cab GMC Help-cheap buy

[sav300]

Ok I'm in search of some help here.....found a pickup I want, want real bad. Not 100% on the year, 73-80, but its in pretty good shape (for the most part).
Here is the low down:
Crew cab
Needs new pas. side doors due to dents
Needs new hood
Interior in good shape
Typical cracked dash and weather door panels
AC
Tilt wheel
Manual window and locks
4 speed standard
350SB stock
4wd
1 ton
14 bolt rear
Not sure on the front end
Runs, supposedly
Needs new windshield
NO rust
No bed
Been sittin for years, drove it to the location and parked it.

Whats it going to cost to fix it up? And is it worth $1000? I'm debating making the drive and buying it. What ya think???
