I've got a line on a good 350/TH350, but the TH350 has the short tailshaft (6"?). What is involved in swapping tailshafts?

IMO you'd be better off getting a longer driveshaft.
To convert a short tail th350 to a 9" tail you first have to locate the parts, you need a tail housing and output shaft.
You can do the swap without taking the pan off but the pump and all the internals have to come out of the front of the trans because the output shaft is like the third part that goes into the case.
Then you have to ask yourself if you want to freshen it up while you've got it apart.
Probably cheaper and easier to get a different driveshaft.

The tailshaft swap sounds like a PITA. Any problem with just using the short tailshaft TH350 and a longer drivershaft? I already have a long driveshaft from an 80's Impala.

Yeah, driveshafts are cheap even if you have to get one made. Not worth the hassle to switch tailshafts.

just run a 2 wheel drive tranny and you should be fine the tail shaft is a little longer on the 2 wheel drives because there is no transfer case
