When measuring the width of my trucks rear axle do you measure distance from backplate to backplate or outside of brake drum to outside of brake drum? Still trying to find a good replacement rear to upgrade my original with.
Thanks!
you need to measure WMS to WMS (WMS = Wheel mounting surface). Some backing plates are dished, some are almost flat, brake drums can be different widths so, the real measurement you want is WMS to WMS. Depending on what you are doing with the truck, you may want it wider or narrower than stock. If you want normal truck tires, same size all the way around, you want the rear end real close to the same width as the front, if you want huge hotrod tires on the rear and deep dish wheels, then you might want the rear a bit narrower than stock...
