[Tigers] SBF Distributor questions

[Dave Munroe]

I had some ignition issues that I finally traced to a vacuum advance unit 
that had a big hole in the diaphragm.

I ordered a replacement from Summit, and recieved a wierd looking unit with 
a cast iron flange that looks like it should bolt to an intake
manifold, has a steel cannister and a spigot for a tube. It is adjustable 
with an Allen wrench through the spigot. Definitely not for my car!

This resulted from the order guy having difficulty finding a part number for 
the proper replacement unit. He asked some questions I couldn't answer:
What is the model number of the distributor? (where is this number located 
and is it likely I could find it without removing the distrib?)

The distributor cap has a slot in the bottom rim to locate the cap on the 
distrib body, but there is no matching tab on the distributor. Is this 
unusual for a
Tiger distributor? As it is the cap is free to rotate, confined only by the 
wires' resistance to rotation.

Thanks for your help.
