Some of you know when changing to the T5, you have a few options regarding the speedometer. You can find one with a mechanical tail section and fiddle with finding the right gears. You can purchase an adapter which will convert electronic impulses to mechanical movement (and from everything I've read this may be a bad plan). You can use one of the electronic speedometers which are tied in with GPS. Or you can adapt one of the units (like SpeedHut makes) which can be set to your particular rear end ratio and tire size easily...a good option but which has the odometer in an electronic screen. There are a few options which use an electronic speedometer and an analog odometer and those can be adapted to the AD speedo case. And when you do this, you will notice 2 things; one---the speeds from 0 to 80 are almost exactly 1/2 of the circle. two---you'll have some extra room at the bottom of the dial (and in a custom made case should you decide to make one).
In line with the last possibility, I've fiddled a bit on one idea for a newish (but more stock looking) speedometer face which would incorporate a 2 inch tach at the lower right and a 2 inch vacuum gauge at the lower left. I've tried to attach it and I think it is ok size-wise. Please take a look and tell me honestly what you think. I've figured out how to extract and use the same exact font which was used in the original gauge and I realize I may need to do some work on those numbers both on the upper and lower sections...
