They don't sell an analog dipstick for the 96 TC Dyna do they?
All I have seen are digitals.
I think that the analogue temp gauges work by using the expansion of the dipstick to create the reading and as such the dipstick needs to be fixed to the gauge
on my Dyna the dipstick is on a sort of swivel so that it can get down into the oil tank and that would make it more difficult to make the gauge as it would need a sensor and a gauge and power supply and would end up very expensive digital read outs consume i think less power and are cheaper to produce
But i am no expert in this area
