[6pack] Which 5 Speed?

James---It's a direct installation, so far as no cutting is concerned. No mods
necessary to install. If you get the kit from HVDA, the instructions will be
complete for the TR6. Probably the 3's & 4's also, but I haven't done any of
these.  I installed the W-58, which has the tallest 5th gear at .078:1 ratio.
It came out of an '83 Celica. Supposedly the '82 to '85 have the ones desired.
It's slightly heavier than the original TR box, but lighter than the TR with
OD.
The hydraulically operated throwout bearing is slick, eliminating all the
hardware between the Clutch MC to the operating fork. (Just when we pretty
much solved the troublesome broken fork pin, along comes the method to get rid
of all this stuff)!

Is the Toyota 5-speed a direct installation, or are additional modifications
required?  And which 5-speed is this?  Just curious, in case...

Dennis---Not exactly "recently" but I installed the Gunst T/O bearing with the
Blue dot B&B disc and pressure plate about 8 years ago. Everything worked well
for the 10,000 miles or so, before I elected to go with the Toyota 5 speed,
which must use a different T/O bearing & sleeve. Mr. Gunst experienced
"whistling" when the B&B pressure plate was turning, and attributed this to
the shape of the cranked fingers. I heard no such sound, and I'm sort of fussy
about these things. Note - the B&B pressure plate is still in there, with the
Toyota disc.

   Has anybody recently put a Borg & Beck clutch in their TR6 and used the
Gunst throw out bearing?

TRF catalogs "recommend" that the Gunst bearing only be used w/ clutches
with flat fingers (ie Luk)

but as per a brief discussion with Dave from TRF, Mr. Gunst's recommendation
may be more political

than practical.  I already have a Gunst bearing and can get a REALLY good
price on a B & B clutch kit -

will this work OK?
