I have a 77 and an 85. The 85 was a california jeep with an i6 auto. Is now a 350 chev with auto. The 77 needs a frame up restore as it was used as a snowplow in Nebraska. The salt from deicing ate the body up. Has anyone replaced one with the aftermarket bodies? It has the 304 3sp. Might be a bit of money to do but at the price they are going for should be worth it.
