John,
Dean sent me a link to your thread. Looks like you have a pretty good project going there. I have a 28LO I am working on. Real basket case when I started. Two years in now and it actually is starting to look like a truck. I'll try to stay following along. I was going to chime in earlier to help with questions, but it seems like Dean has most of your questions answered.

Sounds like you have a pretty good amount of extra parts and I am actually looking for a few items yet. Any group pictures of what you may have extra that I can run my eyes over?
A couple things I could use are door latches, and looking for good trim pieces that go around the gauges. A dash light and rearview mirror. My seat frames are garbage, but if you'd have those shipping would be ugly. I'm sure there are other odds and ends, but that's what comes to mind in the moment.

Going to be a nice adder to your collection. Keep up the good work!
David
