ok this is an area i do accually have alot of experience in partly because i have a '73 commando. but i have a problem, i need more details like is it a wagon version or another version? what engine transmission is in it. you know so i can sort of give you an accurate price. but beyond that i all i can give you right now is a in the football field price range. for a '67-'71 to have the v-6, automatic, be the wagon version (most commonly found), have no visible rust, interior in good shape, everything working, reasonable amount of miles, and good looking paint expect to pay anywhere from 5-7 or 8 thousand bucks. now my jeep i bought for $900 and it was a rust bucket but ran good and was all original. i took it in and restored it to factory specs and had it painted. all that took 2 years then just last summer i had it appraised and the guy said it should sell for around $15,000. not brag but just to compair notes, my '73 has a 304 v8 3-speed and its the half cab truck version. but keep in mind that only 402 truck versions got manufactured in '73 (582 in '72). and most had inline sixes with a different transmission. i think the appraiser was bringing it down to an exact science when he said only like 50-75 was ever made exactly like mine. for '72 and '73 also there was only 3 different versions, roadster, pickup, or the station wagon. but for '67-'71 there was the ragtop convertible continental kit, just plain convertible or "austere" model, the open roadster with half or full length softtop optional, the station wagon version, or the pickup half cab.
hope it helps and i really didnt mean to be so lengthy.
If you can't duct it, f#*% it!!!
