I wouldn't put much faith in what the catalogs say about internal/external resistors. Just go by resistance, if they bother to list it. When mine burned out I took my VOM to NAPA. The helpful guys there narrowed down my search, and I confirmed with the VOM.

I'm confused Charlie, do you want one with 1.1 ohm? If so, NAPA Echlin IC10 fits the bill. Not cheap. They offer cheaper ones but I don't know their specs.
