Short Shaft Slip Yoke 727's in Old Airport Tugs?
The trams at Worlds Of Fun in Kansas City had propane-fueled Slant 6's with short 727's. A buddy that knows what he's talking about (dart4door) has seen them. I don't know what kinds of yokes they used.
When I was at R&R Salvage right before they closed, they had a dumpster full of 8 3/4 housings with the ends cut off. All the ends and axles were still there, in the pile. I asked about it and he said that they pulled all the pumpkins and sold them to amusement parks, because the pumpkins were used to drive the roller coasters.
