The speedometer cable froze up and destroyed the one that was on the four-speed last time I drove it. So I definitely can't use that one again. Since the five-speed was used I dropped it off at a local gearbox guy who only works on British gearboxes. I also gave him the four speed so I can pull the tailpiece off and make sure he's got the creek gearing for the speedometer. As it was my speedometer was off about 10%, so I may need to do some recalibrating. But I'll check that out once everything's back on the road.
