I have bought an instrument cluster from Bus Depot complete with tach and
installed it in my 91. Tach worked no problem just hooking up the existing
wires. I have no idea what will happen in an 82. Would have to check in the
Bentleys. The speedo should not be a problem have changed them with out any
problems. Only the syncro speedos are different as they are connected to the
drive train rather then the front wheel.
