i was wondering if there is anywhere to get a black dash and a glowing speedometer kit or any interior replacementsin black for a 91 cavalier rs

How about not double posting... check e-bay for the guages, and you need to make the dash that color yourself.

you could go with the stock graphite interior depending on what year cav you have. You could get all the interior from a junk yard. Speedhut.com is a good place to get custom gauges.
