I have a 96 GMC K1500 daily driver with a set of 3.42 gears, and an open rear diff with drum brakes that don't work properly unless I constantly manually advance them

I also have the remains of a 2000 GMC K1500 with a set of 4.10 gears, a rear locker, and disk brakes out back.

Does anyone know if it is possible to bolt the IFS diff from the 2000 into the 96? How about the spring perch width between the two trucks, are they the same or totally different? Could I take the master cylinder from the 2000 and use it on my 96's booster to have a properly working disk / disk combo?

The 96 does have ABS, would it get messed up by running disks in the rear instead of drums?

How about the e-brake stuff? My 96 is a standard, so the e-brake is a real asset....

If I am totally off my rocker, lemme know, but if this is something that I can accomplish, I'd like to do so once my semester finishes. The 4.3L just doesn't quite have the gusto I'd like, and I thing the 4.10 gears would do it a ton of good, not to mention the good that gov-loc would do me in the winter...
