The speedo and tach cables have pressed square cross-section ends that are
nominally 0.125" on each side. The Moss replacements are all oversized by
more than 0.010", and do not fit completely into the transmission
recepticle; the corresponding receptacle in the speedo seems to be oversized
as well and poses less of a problem. The solution is to CAREFULLY grind the
square ends down to their specified dimension of 1/8" on a side. The
properly sized end will then enter smoothly and completely into the
transmission. Forcing the unground ends into the transmission and then
screwing on the endcap will compress the cable interior and will result in
fluctuating speedo (or tach) readings, and eventually failure of the speedo.
