I have been toying with the idea of going from the 0.6 mod gears that my truck has to mod 1, I know that pinion is straight forward but the spur is another animal altogether... Is there any difference in the screw pattern on it, should I be able to just purchase one of my choosing and install it on center diff. or what? I just don't want to buy something that I can't use. Now that I am getting the truck fully up and running I want to give myself some adjustability ...
I have just used the speed calulator and came up with a 43/11 to get where I want.... right around 43 mph... if thats true then I am gonna be havin loads of fun....
