Well there is nothing like the garage floor when it is -10 outside.
But I solved a few things. First I noticed only 2 shift rods. It is a 3 speed!! I was starting out in 3rd gear

So it has 7 bolts on the side cover. And the speedo bullet is on the driverside.

So I think I have it down to Muncie 351 or Sag 343. But not sure which one??

most likely a Saginaw three speed. Was likely on "the tree" when stock.

Not sure what year they made the Saginaw 3 speeds fully synchronized so you might have a fully synchronized one (SM326) or earlier.

Perhaps someone else here knows offhand when the fully synched one came in to use.
