Be advised, on that first one the seller says mounting holes are 2 5/8”, which I believe is the spacing for the 216, the 235 mounting holes are closer to 3”. And that second one is an automatic choke model. You probably want a manual choke unless you plan on converting. I have a Carter YF 788s for my 1954 235, and I know the 2100s is also a fit for the later 235
