I found this interesting article from the St. Petersburg Times in 1994. Island Cruisers was a Clearwater, Florida, company that refurbished old right-hand drive postal jeeps for export to island countries where people drive on the right hand side.
Jan and Robin Stach started the company. By the time this article was written, the company had sold 35 jeeps to the Bahamas, Grenada, Aruba, the Cayman Islands and Cancun. They were generally used for rentals. The company had another 30 jeeps in process. The Stachs feel that demand was huge and they hoped to mature into a company capable of producing 500 jeeps a month.
Unfortunately, I didn’t find any additional information on how successful (or not) or for how long the company operated.
Note: Another company started about the same time on the west coast called Safari-Kars
