OK, so I found a shift arm on eBay. Absurdly expensive, but grabbed it because they're so darn hard to find. Is a bench seat arm as well, so I got want I needed.
I think I have a column lined up--somone here from the boards has contacted me--just waiting to hear back.
I think the next thing I need to find is a correct transmission shift hump. They're pretty strange looking...here's a pic....
