im looking to swap my worn out 60e with an 80e and have a couple questions.

1. are there any differences in obs and nbs 80e's like there are with the 60e's?

2. will my transfer case bolt to the 80e or do i need to get a new one?

3. and will i need to resize the driveshaft lengths and move the crossmember?

4. lastly will the shifter linkage work the same?

the truck is a 94k1500 so it has the old hardware instead of a cable.

any input helps, thanks
