Alternative brakes for TR4-6

["Cindy and Terry@ESP" <esp@hypermax.net.au>]

Sometime ago there was an excellent posting on using Toytoa Hilux calipers
on TR6. Does anyone know of a vented disc that will fit. The later Hilux and
landcruiser used vented calipers, and I'd like a disc to match. Any leads
appreciated . I know Triumph Tune, Moss etc offer complete vented disc kits
but these are too dear for this application. What I'm chasing is a disc
rotor only.
