I got most of mine from earlier Camaros the only differance 's would be long and short tail shaft's long shafts are mostly found in wagons and some trucks. Picking which of these you want would depend on driveshaft length wanted. Yours will probably be short so you'd most likely want a short tailshaft 350. The overall length of a short is 27" I just sold my long so can't measure it. I think its about 6" longer. I have been using a 350 for a long time now and never had a problem and I am HARD on them. Be carful laying under the car removing it they are heavier than they look. I used to put them in and out on my chest but either I got older??? or smarter now I use a jack. Probably a bit of both Good luck on your hunting trip.
