Thanks Andy...
He's got it right, it's a right-hand-drive '84 Jeep CJ-8 that is one of 230 that were specially made for the USPS for use in Alaska. It had a factory metal hard top that was sold on Jeep Overlanders in South America and Austrailia (it was never available in the US). I got it two summers ago on a trip to Alaska and drove it back after doing some work on it.
If you're really interested, I published a diary along the way via laptop and modem and they're still available on Rockcrawler.com:
