How common are these 5-speeds anyways? I was just on Wikipedia looking and the info on the W123 and saw that it came with that tranny, and would really like one in the SD. What kind of HP could these trannys take? Quite awhile ago Twizted sent me a PM about the 4-speed install on his SD and said it was near effortless, just extend the d-shaft and the pedal assy near bolted right in.
