You can use a small 20 spline clutch plate from an early triumph 1500
Saloon(Try Kippings or Moss in England for the part) This will utilise the MkIV
Pressure plate and the 20 spline shaft of the J-type gearbox.

Again, all the prop shaft lengths are in the Kipping catalogue(I don't have
mine with me here, does anyone else?), including the lengths that would be
required if you converted a Herald to overdrive etc(very useful).

I think so(But I'm ain't sure) :-)

Nope!!! sorry.

For a J-type overdrive, you DON'T need a relay, as the solenoid doesn't consume
much power, so it draws the power straight from the reverse light switch on the
gearbox.
Good Luck
