Carb Stamped ID Number vs. Casting Number on Back of Main Body

(1/2) > >>

71vette:
I waited over 7 years to find the correct carb number and date code for my 1971 Vette (7041205).  Finally, one showed up on EBAY.  The seller said the main body had been in a box for over 20 years.  My concern is this:  The carb number and date code are correct but there is a casting number in a round circle on the rear of the main body next to where a hot idle compensator would be that reads 7043735.  Just above that it reads RP and just above that it reads GM. 

Does this casting number on the rear correlate to the model year of 1973?  I need to know if I've been ripped off.

 According to my manual, for carb #7041205, would have part #7041658 for the main body, #7041659 for the throttle body and #7042745 for the air horn. It is very common to see part #'s mixed up on Qjet's. This could have happened at the factory. :(

Thanks for the information.  Is your information indicating that I don't have an original 7041205 carb if the main body part number is 7043735?

 My manual doesn't show that. Just shows #7041205 and the correct main body # as I listed above.

Thanks:  I've been looking at pictures of other qjets on ebay and I see that the casting number on the back doesn't seem to correlate with the stamping year. 

If anyone else has thoughts on this, I'd like to hear them.

Thanks.
