You mention you are using a 39 distributor on a 59AB engine the thing that is probably changed is the front cover. The adapter you mention is a Ford part enabling using the early distributors 37-41 on the later camshaft front.

The 59A cam is shorter thus the spacer

Good time to upgrade to a Bubba crab distributor!
