If you're a stickler and want everything to match, try and find one of their older gauges made for the pre-facelift cars.

I ended up installing facelift vent housings and rerouted/cleaned up my wiring to tap into that power source.

I am starting to believe mine may have a boost leak though just from all the things I have been reading. Thanks so much for all of your help. Ill keep you posted with how everything goes. Thanks again
