Brent, two things.
I am having trouble remembering his name, but there is a current JSC member of MARC from Canada that is a stout advocate, and just restored a car similar to the one you mentioned, but I believe it to be a -28-'29. If you have a contact among those guys, I know him to be very knowledgeable in that regard.
Also, here is a link to the English wheel discussion about what you and I discussed.
