Simso - Here's a 2005 discussion in the HAMB forum that mentions some folks using the 35-37 Packard 3 speeds behind a couple different engines. A couple mentioned were specifically Stovebolt 6 engines and one detailed some info about the fabrication/use of an adapter plate.

I found it using the web search "1935-37 Packard 3 speed transmission". You might find more on the subject in a search of your own. wink

Hope this might be of some help. smile
