If you do your own rebuild, make sure you get and use the
installer sleeves for the clutch pack seals.  I wasted too
much time before I gave in and bought them.  A regular
universal clutch pack compressor, a good assortment of snap
ring pliers and lots of patience are the only other
requirements.   Also, use the wide heavy duty OD band as
that is a major weak point if you intend to keep the car.
If you don't mind it a bit firm, you can also help it by
removing the sleeve from the OD apply piston and using the
large piston for a bit more hold in OD.  IMHO, a shift
improver kit is also well worth the time.
