Thanks for those part numbers Leon as I have to pull my dash and will check which tach I have because tach was assembled by Paul ( PTs70 CST) with original parts. It was also reading high like 7/800 with the points distributor when I installed it in the truck.

No problem. Let us know what you find out.
