can anyone recommend a decent guage setup for a '90? i have a 140 speedo. here a while ago i got a MAC cobra style white face kit. what a piece. i am not happy w/it at all. my speedo is off 10mph (by the way how do i fix this) the tach needle slipped so much for some reason that it rests at 4000rpm when the engine is off, and they are spotty at night and hard to see sometimes. i would prefer another white face setup. has anybody got the kit from Mustangs Unlimited where they come already installed and calibrated in a stock cluster w/whites? does the MU kit come w/ all the guages or just the speedo? also can i get the reverse glow (face lights up instead of numbers) kit for my car? finally is it possible to change the backlighting color of my cluster (i was thinking blue) by putting in new bulbs or LEDS in? is this hard? anyways, sorry to write so much but i jus wanted to get it out there. any help or ideas at all would be great. thanks.
