I'm almost done converting my '87 Raider to diesel. The thing that's holding me up is that I can't find a thermostat for my 4D56T. This engine was made in 1995, meaning it was one of the "later" ones manufactured by Hyundai for Mitsubishi. I've included an image showing the thermostat housing. The seating area is 60mm across. Thanks to anyone who can give me a source for this thermostat.
