db duplexers

I have a set of db1145 duplexers that are tuned with not only the cavities but using tuned shorted stubs. I don't have any literature on how to tune them and at the db webpage they don't list that part number anymore. Would somebody have any insight on the tuning procedure used on a setup like this?

Hello.

Decibel Products is located in Dallas, Texas.
I do not remember the address, but they are right on I35, just north of downtown.
The ARRL handbooks, have in the past, covered the duplexer in great detail, including the shorting stub.
