I rebuilt the MkII (MkIIa?) on my Rover 95 successfully without any 
prior experience with boosters. It worked just fine. I did get covered 
with brake fluid when the big piston finally came out, though.

:-(

I got my rebuild kit from a Sunbeam Alpine specialist. I read somewhere 
in the literature that you were supposed to use some sort of castor oil 
to lubricate it. If I remember correctly, I bought some castor oil at 
the local CVS and worked it well into the leather seal. It cleaned up a 
lot and also became more flexible.

The remote boosters I have seen are very high-tech hydraulic units that 
cost around $500.
