I am in the process of cleaning up a 97(...I think) e-locker, ABS rear axle to swap into my 01 and have noticed some differences. I also want to make sure I've noticed ALL the differences so I don't run into any issues when I get my new diffs and swap the axle in.

1) Brake lines - my 01 has two brake lines to the rear axle, I guess for ABS/TRAC, while the 97 only has one. I'm planning on swapping as much of the bracketry for that from the 01 axle to the 97 axle, but I know I'm probably going to need to figure out how to attach some of the brackets. I am hoping I can just take all the brake lines off the 01 axle and they'll bolt right in to the 97.

2) Parking brake - the junkyard I bought the 97 axle from cut the parking brake cable. Are there differences between the years or can I just take all the park brake stuff off my 01 axle and bolt it on the 97?

3) ABS - again, the junkyard cut the ABS sensor cables. Will my 01 sensors work with the 97 axle?

4) This one is kind of a long shot and I am expecting that this isn't gonna work, but can I simply unbolt my axleshaft/brake/etc assemblies from the 01 (open diff) and stick them in the 97 axle with an e-locker? The 97 axle's backing plates are absolutely trashed and I don't know the condition of the bearings. Can I use late model 3rd gen seals in an early model axle housing?

Thanks for any input yall can give.
