Features an 11" front axle set back compared to an RD.

Is that an air vent of sorts in the drivers side headlight bucket or is it just missing a piece?

Nothing is missing or damaged.  That is a shadow from the light source hitting the front of the hood before the recessed headlight bucket.

drove one of the for years ,not a bad truck at all, the front spring is longer than a regular R model, lets it ride a little smoother on the steer axle.       terry

The light bucket is deeper on the grill sides.

RB's were under appreciated and under sold.

Yep, good trucks. Was lots of them here. Dump truck/pony combo's grossing 140,000 pounds with their E7 400's. Still a few going up and down the highway. Bulletproof workhorses just like the original R Model's.
