[TR] TR6 HVDA transmission conversion throw out bearing

[Lee Janssen]

The early Herman van den Akker HVDA transmission conversions used a Howe
hydraulic throw out bearing that was prone to failure in highway vehicles
(Howe indicates they are for racing and not highway use). Does anyone know
what the later version HVDA transmission conversions use for a hydraulic
throw out bearing?
Thanks in advance.
