Zenith 9-90-01/9-90-02 modules

I'm wondering if there are any big differences between the two that would make the 9-90-01 module unsuitable for a 9-57-VCR project. I've been comparing photos of a 9-90-02 to my -01. The biggest difference I see is a couple more metal film resistors and a different pot on the -02. I have extra 9-57 modules I could strip for the adapter board.
