Hi I´m new here and I own a Buick GS 400 400-4 1967 sportcoupé with vinyltop, I had it one month, I want to correspond with other people who had classic Buicks and special GS400. My first question are how can I replace the bulb in my tachometer in the florconsole, I can only find four bolts but there must be more because the console are stuck
