axles, so please tell me how I tell.

well you look at the castings at the end of your gearbox tubes. If they are about 2" then it is short if they are more like 4" then they are long. The casting is the bit the shock bolts toand spring plate etc

Or if you can not tell take a pic of the axel from the brake drum towards where you spring plate joins and post it and someone can let you know
