Hambone, I looked all over for the appropriate shifter boot for the 860 (with a newer trans and completely different shifter than stock) and finally made one for a Peterbuilt work. I know, GMC, Peterbuilt, big difference (kind of like gas and diesel....

) But it worked out and looks appropriate.
I asked Bob Google what he had in the way of 4 wheel drive shifter boots and he came up with lots of choices
