Just purchased an 89 Gt. Was wondering if there is anywhere out there that rebuilds these gauge clusters. Previous owner has chased wires and replaced parts and a couple of cluster won't work and the fuel gauge hangs around the 3/4 full mark and barely moves but owner said low fuel light will come on when low. I'm wondering if maybe the clusters them selves are bad and can they be rebuilt or repaired. Thoughts?

No known entity rebuilds them. They are fairly simple though and can be disassembled and tested and have individual components replaced.

What parts on the cluster are bad other than the fuel guage?
 
I know the 90 and up have the anti-slosh module but I am pretty sure the 87-89's have this and it affects multiple instruments:

Thank you!!! And this is located on the back of the cluster correct?
 
Slosh module only affects gas and oil pressure on 87-89
