Yup.

Depends on what condition your existing MC is in. Odds are good that just a
rebuild kit will fix the problem for another 20 years or so. However, if
the bore in the MC is pitted or worn, the life of the seals will be greatly
reduced.
A word of warning : the brakes on my Stag were in the same condition when I
got it, the pedal would slowly sink to the floor at stop lights. While
waiting for the seal kit to come in, I tried to drive the car to a shop to
have the transmission changed out. On the way, the hydraulics failed
completely ! Later examination showed that both cups had torn through the
base, apparently simultaneously. (Or perhaps the rear brakes had already
failed, since the PDWA isn't hooked up.)
I don't see any reason a resleeved MC wouldn't be just as good or better
than a new one (as long as the work was done correctly), but haven't tried
it myself.
