Just about finished conversion, motor & electrics are in, car drives well. Mechanic said I cannot use cressida tacho b'cause the 7M-GE had an electronic dizzy and the GTE has the crank sensor. This will not adapt to the tacho, he said i need to either get an external tacho(I don't want to do) or see of a Supra tacho(MA70) will adapt or fit somehow. Just wondering if someone else has done this conversion or know someone who has. I'd prefer to keep the interior in an original condition, and use the original tacho if possible. Any help would be great!!!!
