Hot bodies 1/8 diffs

Pin to pin is usually the normal way of measuring, check if Kershawdesigns.com can help- Dan is usually good to deal with. You do want to leave about 1mm at either end of the dogbone/ pin to allow for chassis flex without the dogbones binding up or bending. Once the CD is mounted you can use calipers to check the distance between the drive cups + the depth of the slots for the dogbone pins.

Front drive shaft 83 mm (that is with the 1mm subtraction on each end), and the rear I will need a 131mm bone (minus 1 mm on each end). I found a 83mm Duratrax center dog bone, and a 131 Ofna center dog bone on Ebay both for under 20 dollars. They are on the way.
