That 8-lug rearend likely has 4:56 gears. What is your long range plan for use of the truck?
I got the rear end torn down today. Kind of hard to see the pinion, but I'll figure out a way to count the teeth and we'll know for sure soon.
The truck will have an easy life. I am going to get everything working like it should and then just drive the truck. I'll use it to get feed and stuff at the co-op and other light farm use. Might even use it to pull the old 35 Massey to local tractor shows because I don't think that will be too much for it. I was telling the guy doing the frame that it wouldn't ever be max loaded and worked hard, but he said there was no way he'd let it leave his possession without me being able to load it up heavy and not worry, but I never will. After we can use it for a while one day we'll strip it back down to make a pretty truck. Right now I just want one I can use without worrying about scratches and dings. I might clean and paint the chassis as I go this time around but I'm not committed to that yet.
