1955, If the other CJ3 tub is solid you should very seriously consider buying it and fixing it up with parts from the rusted out Jeep. You can swap out the F engine and use the unmodified hood.
Yes..these two jeeps were almost meant for each other. What ever the one is missing...wheels, engine, windshield wiper motor, hood, PTO, the other has. And what the rusty one is missing, the other has....a solid body....
I just re-calculated the parts from Classic Ent. $2210, and I've almost certainly left a few things out....
The rusty jeep, in addition to a body, needs all the brake components, front and rear spring packs and shackles all around, an easy extra 1K.....tranny is an unknown....The other drives and stops.....
This has been an experience so far but the outcome is still very uncertain.
