to remove drums
First, determine if they are disc or drum. If drum, remove the drum and replace the shoes. If they are disc, remove the caliper (and disc if necessary) replace the shoes and reassemble.
brake drums should pull off if not rusted on.
Easy enough, that can be done from the outside. Remove the drive shaft from the unit, remove seal, replace with new, make sure it seats well.

Not sure but you can go to a Mechanic .
It will bolt up, but the manifolds, flywheel, wiring are different. Also the 1997 head does not have a hole in the rear for the temperature gauge sensor.
I used a T40 on my 1997 Wrangler on the forward brackets of the fold-and-tumble rear seat.
