Jeff,
Please, please, please! If you are parting out this car, I need the tach you have. My 1991 Turbo came with a 993 tach and it has the OBC but no boost indication. I have no idea how much boost I am running.
I can send you my tach, it is fine.
Please PM me at:
dad10@comcast.net
or call me at 703-754-9507
Thanks,
Mark
