Not much building time the last few days, but I did manage to get most of the chassis built. It went together pretty well except for one problem. The gas tank mounts to the frame rails by means of a pin on each side that is at the end of a short extension that comes off the back of the tank. The problem is that if you try to get the tank's mounting pins into their respective holes in the frame rails, the front of the tank hits the differential and the tank can't be placed correctly. So I had so cut off the two short extensions on the gas tank, shorten them, and reattach to the tank. What that did is basically allow the gas tank to move rearward about 1/8", which was just enough for it to clear the rear axle. Other than that, all other chassis components fit like a glove. Of course, none of this will ever be seen once the model is finished... the fenders will completely cover the frame rails.
