Wow, Bill. Thanks for that thread reference. I'm now eagerly waiting until I can recheck my flywheel.
Using some of the counting shortcuts outlined in that short thread, I wonder if it can be accomplished just through the starter mounting port?
Meh, maybe it'd be better to yank the cover so I can inspect the whole area while I'm at it, including the starter pinion/flywheel mesh.
Also, reading further into those posts I noticed that the swing to 12 volt/168 tooth flywheels happened with the 1955 2nd series trucks.
As mentioned, my unofficial records show that the engine is a rebuilt 1957 235 (done in 1986).
In that case, it stands to reason that the flywheel here might just be a 168.
We'll see. Please stand by
