A super short is almost 4 inches shorter then a standard SYE. The shafts definately dont fit between one another. They are the exact same shafts, just different lengths.
DSI is located right here in Calgary. Awsome guys to deal with, and they stand behind their work 100%.
If you take the turn in the middle of the hill to go to modern, instead of going down the service road right to modern, go straight through, up the hill. Past the first stop sign, DSI is just on the right.
You can look them up under Drive Systems Inc in the phone book.
hope that helps
