right Deve, the 2 speed rears are low and lower, but the low rear gear was more just getting the big trucks moving when heavily loaded ... no advantage to you Ed, for the work involved, better to rescue the whole truck

If you look at my post, you will see nothing about making the truck go faster. Here in western Massachusetts, we have a lot of hills and a few lower gears might come in handy when the truck is loaded. That said, my truck is supposed to have 6.17 gears in the rearend. I have seen high ratios listed as either 6.10 or 5.something. The 5.something would reduce high speed RPMs a little, which would be a nice bonus, but I don't even know what gears are in the parts truck.
I was asking how much of the axle would need to be changed.
