That would be my course of action today. I tore apart the dash last night to put in the white face gauges that have been hanging up over my work bench for 2 years. I also wanted to put in the brushed aluminum dash bezel I got for free from my little brother also.
Tear it all down. peel off the old stickers...and the new ones don't fit.
I have an '89 GT. 140mph cluster. The gauges I have are for 90-93, yet they don't fit.
Was 87-88 different than 89? Then it changed again in 90?
Thanks,
Don Manning
