I just bought my first 1987 Turbo-T this past sunday. Some parts of the guage cluster work others dont. I assume to remove it I need to remove the front 4 bolts and get under the dash to unhook all the conectors. Is there any way to pull the guage out far enough to unhook it without climbing under the dash? Also I dont see where there is a temp guage or oil pressure guage on my stock dash?? Are they digital like the boost and rpm guage? where are they on a stock guage cluster?
