RPO Codes for '73 model
How does one determine what options and standard equipment a 36 year old car came with if there are no RPO Codes on the vehicle?
By the way, I'm new to the C3 forum. Thanks

Hi Eddie, and the Cruisers too,
If there is no tank sheet on the tank or hidden behind the dash the last hope is clues from the body's fiberglass tub for a few options. Written on the tub in crayon in various places are notes like p/b (power brakes), a/c (that one is easy), p/w (power windows).
Nothing beats the window sticker and the tank sheet. Here's what you're looking/hoping to find.
Regards,
Alan
Here's a crayon number on the fiberglass tub... 437 indicates a coupe tub.
Here's a tank and tank sheet.

OK, I can figure out the obvious options and I know its a coupe. I have the list of offered RPO options.
Now the gas tank sheet would be something that would tell me "As Built". The car has a 454 ci engine and is a 3 speed TH400. I would like to know what the differential ratio is and and is it a posi, things like that.
My '94 has a "As Built" RPO sheet glued to the underside of the console lid. I thought possibly the '73 would have one stuck somewhere to it.
Thanks guys!

Late(r) C3s didn't have much in the way of special or desirable performance options that would make them a rare collectible car, but it's nice to know from a general knowledge point of view.

Rear is Posi; TH400 required Posi. Ratio is probably 3.08:1. There is a code stamped on the bottom of the differential for the original gear set but that does not guarantee the ratio has not been changed.
'73 and later build sheets are landscape format and larger than the previous 68-72 documents. Here's an example of what you're looking for:
Good luck with the hunt.

OK, I found some helpful info on the Willcox website. They have some code stampings and charts that can help for some options that are obvious since they can only be for a certain size engine, transmission, differential combination, etc.
They have charts with stamped codes, casting marks for differentials, heads, blocks, intake, exhaust, starters, generators and alternators that were used in an original year car. Just click on 'Casting Numbers and Codes' in the menu on the left side of the page.
Thanks guys, I'm learning.

Since this thread is regarding RPO codes for 73 my build sheet shows code VK3 which I think indicates a front license plate bracket, I can't find this code listed on any RPO list that I can find, anyone else have this code on their build sheet, I have the bracket on the car with no center grill behind it.

Technically, the VK3 was not an option in the sense you could order it. It was required equipment for any car being shipped to a location where front plates were required. If memory serves, the front license bracket was shipped in the car and was dealer installed as part of the required GM new vehicle preparation. The VK3 on the build sheet alerted the assembly line staff to ship the bracket with the car.

Although I always wondered what would appear on the tank sticker for single plate destinations instead of VK3. These car would get the centre grill instead of the ugly plate.
