['ol Pinion head]

Two T&D Deluxe Pinion depth tools here. For near 15 years, at least one was in use nearly every week as I knocked out bench build sessions. Only issue ever had with my T&D tool was early on when i damaged the first ones original dial indicator. Ended up buying another dial indicator & magnetic target plate from T&D.

In the mid 90's bought a mid 60's era Kent Moore pinion depth tool kit from a SD Pontiac restorer friend. He had used it a few times over 30 years & thought i could use it. Tried using that setup once in conjunction with an early Pontiac Service manual. End up digging out the sheets from T&D to obtain the correct master head dimension & went what I'm comfortable with. As Larry mentioned in his post, too many variables get thrown into the mix with the use of the cheepee Piniion depth tools, doubt I'd feel comfortable using one.
