Here is the 258 carb on the W30 post we just got from Jeremy.

Stefano,
Interesting cable running to the back of it - is it a add on choke control? Also does it look like it might have the OE heater valve on it? Does it say "Dole Valve" or something else? Still trying to determine if the one that was on my car was in fact the original.


Hope to meet you in Brookfield.

Thanks, this is the second 0160. I can't read the body tag. It is a small attached image instead of a thumb nail.

I have an 7040258 3079 date code carb. that is confirmed and legit. my car was built 11a so I need a 2809 date code carb. I am looking to trade with someone in need of the 3079 that has a 2809 to trade. with mycarb is totally reconditioned and I will trade for one in the same condition are a diff, in money for one not redone.
p m me if interested.

I know the question is old but the RK was a manufacturing assist for the plant. It is much easier for the worker to read a two letter code than a part number.

If anyone has additional data on original cars please post a photo of the carb stamping and the build date.

I have an 7040258 carb with 2659 date code (Sept 22, '69) that is confirmed and has been restored by Sparky and at this point has not been run on my engine. My car was built in early April '70 so I ideally need a 258 that is early Jan to end March '70 . I am looking to trade with someone in need of the 2659 . My carb is totally restored and could trade for one in the same condition or discuss some sort of exchange deal if yours isn't restored. PM me if interested. Thanks.

Good luck finding a trade partner and thank you for posting the ownership of a 2659 dated carb. Yours is only the second reported, mine is the other.

This carb on ebay has a date which I have not seen previously (2939). To me the stamping looks real. Thoughts? https://www.ebay.com/itm/1970-Olds-4...8/133497014740 With this one we are now showing 8 dates for 7040258 production.

I have a service replacement 7040258 with a date code of 3366, so it was built on Wed, Dec 1, 1976. Notice the date code is placed where the date code was placed on production Oldsmobile Quadrajets of 1976 and no two letter alphabetic code because it's a service replacement

Just for interest, here's a pic of the date code on mine before it was restored.

Some really good info here.
So has anyone done a similar posting for the 70 442 4sp 7040256 carb Date code vs build Date?
thanks
