The removable roof went away around 1980, the guy I bought this from had one back in the day, he said it was "neat" but it was a real pain getting the roof back on, it took a long time apparently to get everything to line back up. I had similar problems with an 80's jeep I had once upon a time after dropping the windshield. The frames were so flexy it was very hard to get them straight again.
It does have the neato skylight in the back however.
I've been trying to find production numbers for these, I think they only sold about 25,000 a year, and 90% were 4x4, So yeah I'm thinking these are getting rare enough.
