Ditto, though I use Quartermaster clutches. Other than a difference in =20=

initial expense I can't see a reason to use stock junk--at least not =20

probably easier on the transmission, and the passengers.  The =20
quartermasters are not cheap, though the bottom of the line V-Drive =20

but pulling your engine one extra time would seem to justify the =20
expense. I probably spent more money trying to get stock clutches to =20
work than I have since I switched.  I did manage to screw up my =20
Quartermaster, but that was a stupid error on my part, and it still =20
worked for 12 more race weekends before failing.
