Hey bro, another aussie... beauty. G'day.
You would have seen plenty of those digi dashes, my 89 7M-GTE has one, but only in the right hand drives. The two guys on here that have the "custom" ones they have rewired are converted to their left hand drives.
I dont know that it ok to post other peoples links or whatever so ill just say search digi dash, thatll get you close enough...
Oops, mines not identical... mines a manual so doesnt have the gear lights.
and by the way, nooice.
