Rochester 2G vs 2GC

[plmadding]

I am still going through my 66 C20. It has a 283 and the carburetor is damaged. It appears the top piece is a little warped and the rod the choke flap attaches to is broken.

I am looking for a 2G core, but not having much luck. The 2G is the manual choke version. My question is, can I use a 2GC which from what I have read is the same as the 2G but has an automatic choke and seems to be much easier to find.

Thanks!
