You could probably answer this for me. The one that was on it was a Zenith 11275D, on there now. Next I bought was a Zenith 11280XB, and the third was 10569A it's the worst of the bunch. Have anyway of knowing if these are even the right carb for that truck?
Thanks
My parts books say that a 1954 GMC Model 100-24 calls for Zenith #11618 with manual choke and manual transmission, or any of the following for the HydraMatic in 100-24: #11503, 11578, 11577.

I can not match any of your numbers. :confused:
