Hi there Halcyonhans,
I have just completed restoration of a '66 A-code coupe which was completely original right down to the Borg Warner T-10 4 speed manual gearbox.
I had it professionally converted to RHD but convert the cable clutch to hydraulic myself using new master and slave cylinders (PBR) and an XB Falcon hydraulic line picked up from the wreckers for $20. The hardest part was designing and making a bracket to attach the slave cylinder to the bell housing to actuate the clutch lever but managed to come up with a good design after making a couple from cardboard as templates.
I guess the vast majority of early Mustangs were autos because back then they were popular in the US. Here in Australia most early sixties cars were still manual.
One of the problems with Mustangs with manual transmissions is the difficulty in fitting headers around the clutch lever and associated working parts and of course a RHD conversion means all the original mechanical clutch parts between the fire wall and the bell housing can't be used as they are on the wrong side relative to the clutch pedal.
There are only a couple of gearboxes that I know of which will fit up to the early Mustangs, the original 3-speed, the
T-10 4 speed with reverse lockout lever used up to the 1967 model (even the early Shelby had the T-10 contrary to popular belief) and of course the good old 'top loader which took over after 1967.
I hope this is of some help to you and if you need some help with a clutch bracket, let me know.
PT
