[Tigers] JH-Who is Best at Sleeving a Brake Master Cylinder? Not Tiger Related

[deiland1 at elp.rr.com]

I'm working on replacing my old, tired, worn out brake booster and Master Cylinder with aftermarket American made parts. Only issue is the smallest bore on the Master Cylinder I want is 1" when the OE had a 3/4" bore. Since the OE is NLA I thought I would buy a new 1" bore MC and have it sleeved to take a Triumph TR6 internals so it will be easy to rebuild in the future and be close to the same pressure as the OE. The TR6 is a 13/16" bore so it works fine from what people have told me who have used them. I have a couple of questions: 1) What is the difference between a shallow bore and deep bore MC and how would I know which one I would need for my replacement?;and 2) Who would you recommend to sleeve a brand new polished aluminum MC? I'm looking for a quality job that is also done very carefully so not to damage the show quality housing. I am aware there are some shops out there that have burned a few people so I would like to hear about the best shops that I can trust.

TIA,

BTW-this is for a 1974 Jensen Healey, but I know a lot of my old friends from the Tiger list are very knowledgeable on these kinds of subjects so I thought I would see if anyone wanted to add their 2 cents.
