What do we need to do, to get our 1,400 foot Jeeps ready for the higher elevations? In 1979, I took my Indiana CJ-7 to Loveland, CO and it was a PIG in the mountains. And when I brought the J10 west, I definitely noticed the power loss @ 7,000 feet (was still very strong, though).
1985 J20=The powertrain donor to my M677. But thinking about resurrecting the carcass as a short wheel base, topless, bobbed J20.
