amt kit , I added the rearends,wheels, and tires from a revell of Germany w900 kenworth.
the v-8 cat is also from the w900 kit. the front steer axle, tires and wheels, are from the monogram snap tite w900 aerodyne kit.
for the sleeper box I cut two roofs off two monogram aerodyne kits, put them together to get the correct profile, then scratchbuilt the rest.
now have to just add the rest of the details.
