I would prefer the mechanical speedo so as to not have to go with an expensive adapter to connect the speedo . I have the t5 page with all the identifying application numbers as well as another page with the exterior dimensions as far as length , shifter location , etc. What I don't have is something with the dimensions of the face of the tranny where it connects to the bellhousing . I'm talking about bolt holes center to center , etc. .When I go to look at the Isuzu tranny , if it doesn't have a number that matches one on the t5 ID page , I would need some measurements to compare . Does anyone have such info ?
