I knew about the input shaft rings but not the breakdown. Unfortunately, the trans is still in the truck and although I can see the clutch and bearing assy thru the inspection cover, I don't think I can see the rings without pulling the trans back at least.
I need to slip the clutch a bit to get it going so I'm thinking it's got the 2.54 1st gear.
