Wow, you're the first one I've heard from who still has/uses that paddle/boom crutch.
The one for my boat was long gone before I bought it, so I can't help you there. In particular, I've never seen the part you call a "key". Would you care to upload a picture here? (See the "Forum info" section for how to). However, what I don't understand from your description: are you missing a piece from your broken paddle? Because otherwise, you should be able to determine the length. The one place that stocks many of the genuine DS parts is DR Marine. I'm not sure that they have a paddle in stock, but the owner is rather knowledgeable about early DSs.
Another way to determine the length required would be to rig your boat and put the boom into the location it would have been held by the boom crutch and then take a measurement.
