The IH dealer should be able to call you back with the right information if you gave them the VIN. If not, the Wisconsin Historical Society has the old line set tickets by VIN, and I think they have them for the mediums as well. They will be able to provide a build sheet for about 20 bucks. They're on microfilm, so it costs money to print them out. The type of transmission will be on that line set ticket. I don't know what type they used on the loadstars in those days, but I was thinking a T436, which would have a direct 5th gear and a deep granny gear.

The number I have is 608 264 6410. I don't know how old it is, but it's probably still good.
The serial number of the vehicle is also on the frame, driver's side, just behind the front spring hanger, outboard.

Just found out that a t 699 will work with the t 496 and is a better trans. Found fork in ILL for 190.00 but i think i can find cheaper i hope. I would buy a hole trans, they go for 350 if they have one here in missouri. But if anybody knows of any let me know
