Maybe someone else with a '75 Canadian delevered car can answer this. Does your odometer/trip odometer measure in miles or kilometers? My outside edge of my speedometer measures in miles while the inside numbers are in kilometers. This would lead me to believe that the odometer also measures in miles. However, I've noticed lately when resetting my trip odo after a fillup that it seams to measure distance in kilometers. I've taken some highway runs of a known distance that should have measured about 60 miles and found the trip odo to measure the distance as 100 miles (km?). I thought that Canadian cars didn't switch the odometers to km until the 1978 model year.
 
I also thought '78 was the changeover year as well. Perhaps your cluster has been changed. Best way to verify (and most fun) is to head down to the Motorplex at Grand Bend where you can check it a 1/4 mile at a time. lol
 
You can also check this with a "smart" phone by downloading a gps app that measures distance/speed and going for a drive on the highway and compare its results to your odo. If you don't have a "smart" phone, maybe you could borrow one. If you were closer, you could use mine!...or is that, if I was closer to you?

I guess a portable GPS unit would work as well.
 
yeah there's a ton of different ways to verify speed and distance. On major hwys there's measured kilometers to check by. 36 seconds for a kilometer @ 100 kph or 60 seconds @ 60 mph..

Having thought about the dials, I'm pretty sure they registered in mph on the outside, larger numbers, and kph on the inside smaller (orange/yellow) numbers like case described -- and the odometer would be in miles.

Easy enough to check with just the car: just drive 60 mph for one minute. You should have driven 1 mile. If it's registering in kilometers you will have travelled 1.62 kilometers.

Thanks for all the replies guys. I took the car out for a run this morning and paid closer attention to the odo and trip odo. I watched the odo at 60 mph and it did indeed roll over once in a minute. The trip odo has an issue though; the 10's roll over two at a time every time the 1's roll over once...in other words, when the car accumulates 9.9 miles on the trip odo, instead of the 10's rolling from 0 to 1, it rolls from 0 to 2. Probably needs some cleaning in there or replacement. The odo is working correctly though.
