Swamp Dwag are you ready to receive some snow? It is on sale now $500. per tractor trailer load..haha. Did you get you speedometer done yet? I was talking to a mechinic today & explained to him what you were trying to do with your speedo.
He told me that the cable for the speedometer has a square end
on each end. He said to hook it up & run a measured mile & check to see how far it's off. Like if it's showing 80 %, you would change
color of the gear in the trans. For instance if you had a gear with 20 teeth in now you change for a gear with maybe 21 teeth to make it right. He also says the gears are color coded. It don't matter about the rear end ratio or tire size.
I thought I'd ask him because he used to deal with transmissions
If you have trouble getting a cable long enough he said to see someone that does meters for taxis. They can make a cable different lengths & put the square ends on for you. Apparently the ends of the cables are all the same. I thought this may help you. If you already have it done, it may help someone else.
Did you & Houlio get those clips done of the rally?
