I purchased a NOS original 60-64 Light Truck 292 Y-Block Distributor on Ebay on Wed .Autolite DA-647 in the Box. Not rebuilt but later brand new Ford replacement Distributor with the Triangular shape Body below the Bowl.
"You" (as the kids say these days) "Suck!"
Gotta link? I looked for it a little while, couldn't find it. Just so I can get depressed and think what might have been.

Last night checked mechanical advance with a light, hooked the vacuum advance back up and took it for a highway spin. Seems to run better than ever. Think I can bump up the initial maybe a little bit from 10° or so and loosen the springs for a little more zip but it's pretty good right now.
