Anyone have part number/source for odometer stepper motor 88?

Same here, only mine's an 87gt.

Actually, I meant the trip odometer. Thanks.

I found this, it's from a 95-99 Tahoe. It's the drive motor for the trip and odometer both.
It is interchangeable for the Fiero both motors but the Fiero connector needs to be swapped over.
I used a spoon to push the motor posts down while I pried the disc off the back of the motor. I tore up the first motor.

88GT resurrection in progress.

I replace the servo motor for the odometer on my 85GT last year. I found the part on a Corvette site Batee.com part number A010. It took about an hour to replace it.
