hay zig what part of the country are you in?
i think that i woul get it running, I mean if you can push it and it rolls, then it can be rebuilt, fix it then go find the year ect that you want, and start rebuilding Her, I have a 57 chevy pickup off road rig at my dads hous in NC "i live in "WA" there is more welding and bondo on that thing then there are from most totaled and rebuilt trucks, i mean i SMASHED the drivers door on a stump in the swamp, and took 2 54 ford doors sliced them and welded them back together, and it looks like a 57 chevy door. have blown 2 motors in it have a spare tranny under the seet, and have lost more parts in the swamps of chowan county NC then i could shake a stick at, but never had to walk home. Soon as i can get a somone that can tow it 3400 miles weighing in at over 2 tons , do to the Military mopar 1 3/4 ton full posi running gear "still brass bushings thoe" i will make the trip to bring it back to were it was built
it is the spirit of the rig, new motor, or body, or any other piecs, its just a little like plastic surgery!
sorry for rambling but that is my opinion.
ps it will live agin, as said before it is only dead when it is beyond recognition "bieng hit by a train" see that happen to a jeep once and it was dead. the guy driving it liveed but his truck was rosted tosted and left in the rain.
