Buyin' A tranny from a boneyard is just like buyin' anything else from there. You just gotta look and get a good price and plan on rebuildin' most of the time. Sometimes you can find a good one, but I don't know what the boneyards are like in Norway. Do you have a preference for number of gears? An old 3 speed or older 4 speed will use mechanical linkage to engage the clutch, most newer 5 spds use hydraulic, so you would need to think about hooking it up to the pedal and mounting the clutch master cylinder. Not as bad as it sounds if you are pretty handy. I'd probably try to find one out of a late '60's early '70's GM car. You'd probaby find a muncie in most of those. Some of the later models used a saginaw and they worked pretty well too, not as tough as the muncies though.
