Chassis fairings on retro 80s trucks

To be honest, if I were to buy an older cabover that had them, I would remove them. But that's just me.

 

I think you've got a sharp looking truck as it is! Maybe stainless/chrome bumper, and that thing is sweet.

 

So this is always an "opinion" type of topic. In my OPINION, you can do a lot of damage to the looks using other make and model parts and pieces, unless rat rod is your preference.
Chrome and stainless seem to never go out of style.
For aero and fuel savings, my OPINION would be to go to the plastic store and pick up a couple sheets of uhmw or the like, and start cutting out your own. Start with cardboard and tape to get the idea of the look before cutting the plastic, then hack some brackets to hold the plastic pieces on and use it for a few miles. Get some feed back. Then make some permanent parts from metal or fiberglass.

That KW, in my OPINION, don't look bad, but has that "repair from an accident" look to it. In my eyes that is.

 

Might go from 3.5 to 3.51 for the quarter…

 

I'd put that money towards polishing the tanks and maybe a stainless bumper.

 

The 372 intrigues me.

 

Well right now we all like it, but if you add fairings it would certainly be a lot of work to make the truck ugly. I pulled fairings off my Freightliner never noticed any difference on fuel mileage.
