Converting tacho from 4 cyl to 6 cyl?
I recently acquired a 10,000rpm vdo tacho which looks exactly like those used in the 3.0RS & early RSR models but it has 4 zyl stamped into the circumference of the case (can't think what it might have come from). Anyone know what's involved in converting it to 6 cylinder?
