Autometer's Steet Comp series match very closely. Some say Defi are close too. The only gauge cluster that will fit in the 1 din radio spot is one made for Saab. Search for "saab gauge holder" and you should find the part#. It will hold 3 52mm gauges.

Omori also sells a 3-gauge din panel.

scroll 2/3 way down

before doing any modding do:
1) change fuel filter
2) new plugs and wires
3) boost and water gauge (others only if seriously modding)
4) eliminate the AST

These things will help your car be prepared for modding.

Well the good news is I am getting 3 new gauges today. The Water gauage and Boost guage and I need a 3rd, I guess I will get a fuel economy or Altmeter.
I ordered the Saab panel today also. I checked my maintenance records from previous owner, the plugs are the NKG's and were replaced around 4,000 miles ago, when they replaced some of the seals and hoses and waterpump in my car. I'm not sure what the AST is. I guess I will search that.
