I've got a '78 w/ 403 and can't seem to find the right rebuild kit for the carburetor. The parts guys are asking for the Rochester number but what I'm reading from the top of the carb (17058715) doesn't match any Rochester numbers that we can find. Any suggestions?
Thanks

The carb number is actually stamped on the drivers side of the carb. On a 78
with a 403, the carb number should be....
17058254 for standard emissions.
17058559 for california emissions.

Ray is correct.
The numbers in the small circles are castings numbers, not the carburetor number.
Check on the drivers side of the main casting, right above the secondary throttle shaft.
There should be a carburetor number, Plant Code and Julian date stamped on the casting.

The carburetor in our 78 403 is 17058559. Sometimes carb numbers change during the year. This GMC was built in January of 78. Our other 78 403 GMC was built in December of 77. I believe there's 122 VIN's between them. I'll check the carb numbers on it tomorrow. Be interesting.
