I have a NOS mini progressive controller. Built in TPS and RPM window switches
It's a pretty small unit so it should go pretty much anywhere. Price tag wasn't too bad either (around $250). In the future I wouldn't mind getting one with a nice screen and put it in the cubby hole.
Here is one installed next to some other components so you can get an idea of the size better. (pic swiped from CapeT/A on ls1tech).
