jaysm35a2 Posted June 18, 2011 Share Posted June 18, 2011 I was going ot ask a few weeks ago. I found a "68" U model Mack. It was a tractor now a dump. The horn button says Mason Dixon Truck Lines , 10 speed tranny. In the cab it shows no sign of the truck ever having a speedometer. I have looked all over and cant find a thing. Would this be correct or what am I missing? Thank you Quote Link to comment https://www.bigmacktrucks.com/topic/19447-68-u-model-speedo-question/ Share on other sites More sharing options...

jaysm35a2 Posted June 19, 2011 Author Share Posted June 19, 2011 I thought so also but I cant find any sign of that either. What did the tachograph have that would be better than the speedo and tach? Ive never asked that before. Quote Link to comment https://www.bigmacktrucks.com/topic/19447-68-u-model-speedo-question/#findComment-79907 Share on other sites More sharing options...
mowerman Posted June 19, 2011 Share Posted June 19, 2011 its a tattle tale stool pigeon,we used to call them,put paper charts in them,and wind the clock,,so the company can tell when,and how long you stopped,and how fast you went..on that model,it was probably right behind steering wheel,next to tach Quote Link to comment https://www.bigmacktrucks.com/topic/19447-68-u-model-speedo-question/#findComment-79909 Share on other sites More sharing options...
