No anything could have been possible with Jeeps if they were asked to build a "special" Jeep.
Some of the "Grand Wagoneers" (late 80s) could have been built with bench seats and manual roll up windows. I think some were built for the US Forestry Service and one was one Ebay either last year or the year before. A very ODD jeep it was! lol
So it might have been possible to have a 2.8 engine in years other than
1984, 1985 and 1986, in the little Cherokees. I was not sure if the exported Cherokees had something other than what was stock for the USA market.still learning! later, dave AKA vwdoc1
