1989 International Dump

Looking at buying an 89 international 1954 at an auction. I ran the VIN through my local dealer and it has the 210hp 466 with a 5 speed manual trans and a 4.44 rear end. My dad went and looked at the truck and said it is not a 2 speed rear which is surprising since I thought most all the 5 speeds around that time were 2 speed rear ends. The dealer said his info said the trans is a T364 discontinued. I am not sure what that means and he didn't seem to know much either. I am assuming that since it is a 5 speed that it is a Spicer trans. The truck is a 32k GVWR with air brakes. I am wondering if the gearing will be low enough to handle heavy loads off road around our farm. Our current truck F700 has a 2 speed rear that we use a lot off road, but it is also a small gas engine with very low power. I guess my question is does anyone have any info on this trans. I am curious about the ratios. I want to make sure that a 4.44 rear with only a 5 speed will be able to start off with a heavy load off road. I would prefer a 5 speed with 2 speed rear, or even a 6 or 7 speed but beggars can't be choosers. I have looked for a long time to find a 466 with air brakes and 16' bed in my price range and there isn't much out there. Lots of juice brakes but with the towing i need to do air brakes would be much better.

Some of those came with ten speeds. If it is cheep enough and won't do that job 10 speed or two speed it. That is not an off road set up.

Ok, well looks like won the auction. I won't pick up the truck till next week so it will be a week or two before I get to try it with a load. What all would be involved in switching it to a two speed rear? Can you keep the same rear axle and just change out the third member and then add the switch and electrical? Also on different GVWR trucks are the rear axles actually different or just heavier springs?

Sorry for all the questions. I know how to work on jeeps, light trucks, atvs etc, but fairly new to the medium duty world.
