Catalog appearances for this part run from the early 1970s through the end of that decade, showing up in the speedometer and tachometer figures alongside the drive gears and spindle it works with. If you're chasing a leak or noise out of the tach drive gearbox, this plug is one of the small items worth checking along with the gears themselves.
It's a small, inexpensive part to keep in the bin, since a missing or damaged plug at this spot can let the drive gear walk out of place or let dirt in. Give us a call if you're not sure which plug your gearbox takes - there was more than one style used over the years.
