Thats awesome, dooly from Ledmod.com makes heaps of gauges for the celica crowd. I had a set based on the Ferrari Enzo gauge face and it makes a wolrd of difference to the interior. It looks so much more modern and it was great quality.
Wish i could him to make some for the M coupe.
Here is a pic from my old celica. I loved the center tach.
The gauges would light up blue and the red line would light up red. Wish i had a good pic of it all lit up.
