Reply to "speedo connection"

Sorry- I missed that. The big nut on the right-angle adapter can be tightened, but only by playing around with the starting position of the nut on its threaded shaft in the adapter. It's harder to describe than to do, but if you unscrew the adapter nut all the way, then continue to "unscrew" the nut another turn or so, then bring the unit back down onto the transaxle stub, it should tighen up more-or-less-tight. This is the source of some oil seepage but I'd never heard of it causing needle fluctuations. I also rerout the speedo cable to produce larger more sweeping curves under the powertrain so as to not make the cable work too hard as in the stock too-tight routing. This seems to make a difference in smoothness, at least at low speeds (my opinion). You can continue this nut-position adjustment as required, as long as you don't disturb the small 10-mm bolt below the adapter. This is the extension shaft retainer bolt and if removed, it will release the shaft to fall inside the tranny, to your great cost at retrieving it.
