If you changed to Dayton's using the other truck parts, I believe you could swap the hubs and use your current housing. You would have to pull the axles to do that after which it would be simple to swap the center sections. That way you would keep your current ratio too.

Someone who knows better will correct me if the hubs cannot be swapped, but I am pretty sure they can be. My 69 T-50 has Daytons and the bearings and hub internals look very standard.

Well it may be time for an update. i found a set of the accuride 22.5 rims, with nearly new tires on a 76 c60, so that solves my 20 inch rim issues. as for my 6.5 swap i have run into an issue with the clutch. it turns out the biggest flywheel i can find is a 13 inch for the 6.5, and the smalleat clutch with my 1.5 inch 10 spline input is also 13 inch. i will have to look into getting one custom made for it. however i am really impatient so i picked up a 366 to get the truck on the road in the meantime.

I hope when you picked up the 366, you had a close place to put it down.

I went to a local clutch place(Denver, CO) a few years back and they put a 1.5”, 10 spline center in a disc that was used, normally, in a smaller clutch.

Perhaps you can find a place near you who does clutches, it is not rocket science.

that seems to be the avenue im going to have to go down, however my nearest place for something like that is 5 ish hours away. i am still planning on doing it, but will have to stick to the 366 for this year, as i need my picker for air cart tires in the spring.
do you recall roughly what they charge for making the disc?

I don’t remember, but it wasn’t much. Can you just ship a new disc to you?

That was the plan Ed. if im doing that i should just call the shop where you went, probably save me some explaining here. if i recall i had asked about it when i was looking for a pto gear from the shop up here, and they said no. which is why i was looking for a factory part number to just order one. could you pm me the name of the shop you used?

That shop is no longer there, probably done 20 years ago.
