I received my Mack cabs in the mail a couple weeks ago. Going to build an old school tractor and the other I'm thinking of a couple of different things still.
I'm on the fence still if I'm going to buy a king hauler kit to be a donor or if I'm going to go complete scratch and buy everything individually. Most the tamiya parts are pretty toyish looking. I may be forced to run Tamiya rear ends since the impressive RC4WD top loaders are way to big for this scale.

We will see which way this build goes.
