Thats a good deal.
JUst remeber that teh 1200 auto from 74 or 75 onwards is the same as many fitted to other jap cars like mazda rx7 even.
If you do a search of the model no on the net youll be surprised at how many other cars have them. You could also use the upgrade model with the 4 speed but youll need mikes talent in electrics to hook up the electric overdrive setup which doesnt run off a computer as I originally thought.
Even my old 4 speed auto liteace had a carb and 4 speed overdrive.
