Jarge,
Yes, they are. But the grill and the Budd wheels are throwing us off. And the interior being somewhat of an olive drab color rather than the standard Mack green.
I think Henry is going to contact Mack with the VIN and that ought to settle it. Still fun to try and figure it out on our own, though.
And to think about how solid the truck is and that Henry paid less for it that what the siren and BeaconRay light would go for on ebay... He got a good deal and saved a neat old truck from the crusher. I think the engine alone would provide enough steel for three Avalons!
