It's Awesome in its Weirdness

Came across these Mack pickup pictures. I didn't know Mack made weirder pickups than IHC.

Proportions look a little off, like someone made a pickup out of a big truck
Sound familiar?
Looks like they used your idea but instead of using a front fender on the rear, they used a rear fender on the front?
Those rear fenders would work nicely on my C35!

It's pretty well done. Proportions? What are THOSE?
