What vacuum pod # goes with 1970 LT1 distributor, etc
 

Is there a DELCO list of which part # Vacuum Pod goes with which distributor application

I have a D1382 / 1115355 that indicates it has 15 degrees of advance

I have a D1383 / 1115360 that indicates it has 12 degrees of advance

I am restoring 1970 LT1 350 distrib and a 1970 L78 Distrib

Found the list in Chevrolet by the Numbers 70-75 page 216
