Cord S/C AA-25 carburetor

Thanks Pat.

It seems that for what these carbs are bringing these days, if the main difference was just the linkage I figured someone would have had a repro linkage made to convert some Caddy AA-25s to Cord. Has anyone done that?

Based on my limited knowledge, my custom beverly has a corect Cord AA-25. I also have a couple of Cadillac ?? AA-25's. The difference is in two places. The bottom casting with the throttle plates have a different linkage arm on carbs other than Cord. The top casting on other cars have a vent stack also, and Cord does not. I think their are a few other items also. The throttle arm seems to be the most important difference.

Wondering if anyone can help clear up the differences between the AA-25 for the '37 Caddy on Ebay and the correct one for my S/C? Photos would be great if anyone has some. There seem to be many AA-25 derivatives.

My car had a Zenith installed at some point and I'd like to find an original AA-25 for it.

Thanks!
