Tom,
I believe that a '71 would have originally had a free wheeling gearbox. Whether it still has it will be interesting to find out - they had a reputation for being very...breakable. Many/most were probably swapped out for later transmissions (Saab did a major overhaul of the gear box design in 1972).
I have a 2-stroke car with free wheeling (which is fine for that, the engine has no torque) and I think the biggest trick is that you have to learn to slowly feather in the throttle when you apply it so that the engine doesn't rev up from idle and then suddenly engage the freewheel with a "bang". That puts a lot of stress on everything. So you have to learn to "match revs" a bit.
Fun stuff! If you actually get a car with freewheeling that works I certainly wouldn't try to get rid of it, although some might advise that - it's a cool feature that made the early cars unique. Of course it serves no purpose on a 4-stroke engine - the reason for having it is to prevent oil starvation on over-run in 2-stroke engines. Why Saab elected to carry it over into the 99 is a mystery.
Best,
Gary
PS - send me an email off line and I'll get the parts book to you.
