Ok folks i am the owner of a 1972 Australian 3500 that has speedo problems.
now this is going to get complicated, so i will try to keep it brief.
when i got this car, the speedo was not connected and it runs off a GPS tachometer, and obviously i would like the speedo to be working...... now the fun begins
it was an Auto and had a LT77 fitted, so i duly got the right cable and connected it up, to gat a whopping 24 mph at 40.......
no problem says i, its obviously an Aussie box from after 1974 when they went metric, so if i just get the right gear i can convert it.....
now we get to the meat of the problem, i searched through the forums as you do and got a gear with the right number of teeth, fitted it and .....nothing.
so i bought a second one, and fitted that, nothing, then i had the presence of mind to measure the diameter of the two gears....
my original comes in at 25 mm and all the others come in as 21mm.... is there any way that i can get the correct diameter gear or am i going to have to go the converter in the cable route?
