Aztec/GP needles don't fit 92-94 clusters.

Just an FYI. The shaft is too narrow on the stepper motor.

possible to mod to fit?

Are you sure? Try reaming the hole out with a safety pin.

The shaft for the gauge motor is too narrow for the post on the new needles, unfortunately. The older needles use a brass press-fit, not plastic, and there isn't really a way to do it, unless I spend about four hours with a drill and some epoxy.


No biggie, just putting it out there for "tribal knowledge".

While I'm adding things- 1993 and 1994 odometers have incompatable shaftdesigns. The 93 uses a notched shaft with a spring between the odometer and trip meter, and the 94 uses a d-shaped shaft, with a plastic link. Happily enough, they entire assembly does swap and function between the two.

Sorry to hear they won't be able to work. That is good info to know in the future.

I still think you should make them work though. You will be the only person that has them in a 88-94 dash.
