Still more questions than answers. Lots of detail differences between manuals:

Autolite IBJ4001C Centrifugal advance 32 degrees
Per Studebaker Vacuum advance 22 degrees
Shop Manual Timing 5 degrees BTDC

5660 - AL IBJ-4001C timing 5 degrees BTDC.
vacuum 20 degrees @ 13 Hg.
centrifugal 30 degrees @ 4000 rpm.

Delco 1110865 Centrifugal advance 1-3@450, 7-9@900,9.5-11.5@1600, 11-13@2000
Vacuum advance 7-9" starts, 8.75@14.5-15.25"
Timing 10 degrees BTDC

5680 - DR 1110865 timing 10 degrees BTDC.
vacuum 16 degrees @ 15 Hg.
