1st when replacing with the taper bearings, i had to use a dremmel to cut the lower race out of the fork stem ( not all the way but enough to chisel off the part) get rid of the lower seal as well.
the outer cups are the same, but the inner ones are diferent (I'm trying to remember now!!)
drive the bearing in with a poly drain pipe, they can be cut shorter and are sacrificial ( i think they are 2 1/4 ")
use plenty of grease and don't tighten down too much as you'll over load them just enough to take out any slack!!
2nd fork oil seals - are a pain to replace and you need to strip down the stantions via a allen bolt under the lower fork. if you can do this before taking off the springs and you can then quicky "snap" off the bolt before the whole stantion gets to move around with it. otherwise you need to make a tool to hold the innards to undo the bolt! ( do-able though)
you use gentle heat to get off the seals and use a pry bar and soft cloth protecting the soft alloy ( this is after the stantions are taken off). if it still won't budge, self tapper screw into the seal and pull the F*ker out!
for gaiters, you need to measure the top of the lower fork mount and stantion ( which is 33mm) and ask the vendors.
