Are these four speeds common at all? Would you know where I would be likely
to find one of these? and lastly.....does anyone know what ratio these are.
I am also looking for a CR box as I used to have a TRD one in my corolla and
it makes driving many times more fun, but I'm having trouble finding a
Datsun or Nissan CR box of any description.
Thanks all.
Russ
