I've still got the fridge I took out of my 1970 Caravel
. It was working at the time, but lots of cracked plastic and tired gaskets.
I'm traveling, so can't get the details, but it was about 38" high. If that sounds like the right model, I'd be willing to see if I can remove the baffle and send it. It'll be two weeks from now before I'm home. Let me know.
Cherokee RV in Denver has a ton of old fridges on the lot. They might be willing to find the part, also.
