Re: The "seldom seen" RPO thread
I’m not sure what it took but I’ve seen 4-5 of them on here over the years.

Build location was assigned somewhat geographically based on where the vehicle order was originated, but that was overridden if the truck had an option that was only built at one or two specific plants. K

Re: The "seldom seen" RPO thread
Sure. U01 was free expression. You could get it on anything just by checking the box.

Re: The "seldom seen" RPO thread
Codes that do not follow the typical "alpha-number-number" arrangement are "SEO"s: Specialty Equipment Options.
They are normally reserved for medium and heavy duty trucks, which were built at slower line rates and with much more proliferation of options, or for police/government/special contract vehicles, like Penske and Uhaul. K

Unicorn ‘68 K20:
A85 shoulder harness. Didn’t know you could option those as early as 68. Another truck with a Positraction FRONT axle. Notice how both the no spin option for the rear and the posit traction for the front do not have typical alpha number number codes either. Steve weim55 Colorado |

Re: The "seldom seen" RPO thread
Yes Chevy did, starting in '63, C 20's with duals had the coil set up. Not sure when this option ended. I thought the reason was for a softer ride with coils with stability of the duals and lower ride height. Never seen a Chevy or GMC 3/4 ton factory dually with leaf springs.

Re: The "seldom seen" RPO thread
You couldn't get U01 without the raised pad roof in 69-72. U01 was available in earlier years also, but the roof was smooth and the lights were Yankee 77 style (with chrome) not fireman's hats. You could have added Yankee 77 style lights via aftermarket or as dealer add-ons to any truck that wasn't originally ordered with U01 on a smooth roof.

Re: The "seldom seen" RPO thread
My dad had a 71 K10 with factory U01’s with the raised pads. They aren’t all that common but they are definitely around.

I thought the small wheel carrier was pretty cool.

Re: The "seldom seen" RPO thread
Love the "seldom seen" thread idea.
Wish more people would post their anomalies as you know there has to be someone out there that will have an explanation for them........someday : ) I have fished through the SPID thread (also great) many times. Thanks to all the members who post SPID pics. It really helps. |
