does anybody know the proper way to disassemble a nitrous gauge?...my lighted gauge went **** up & I found a non lighted one on Ebay for $200 less [brand new]..if I can get the gauges apart & swap out the faces I'll have a lighted gauge...electric pressure gauge, mounts in the "A" pillar.the gauges are autometer & identical except for the light hole & face. thanks.

 

Ricky?...Dave?...anyone have an idea?
