The difference in the drives that are listed is the different mounting studs lengths, or lack there of, for the governor. The basic drive is the same for all those part numbers just the governor mounting stud setup is different. Looking at a picture of the Jihostroj prop governor, I would order the one for the Woodward governor as the mount looks very similar if not exactly the same as a Woodward or the one without mounting studs and just use bolts. Even if you were to order the wrong studded one, its easy enough to remove the mounting studs and use bolts to mount the governor. Following that logic anyone of them would work. I have no real experience with the issue just basing my answer on my engine experience and the pictures of the governor.
Good Luck, Mahlon
