Carter Single BBS Issues

So I got the parts from OCPNW and I think he sent me the wrong choke pull off.. Any idea how to handle it? The box says 66 and I have a 67...

I did get the old choke thermostat working correctly. I took it off and tried to use the new one but it would hit inside the manifold. I would have to enlarge the holes to get the new one to fit. After working the old one back and forth uninstalled it seemed to work like the new one. After reinstalling it the choke butterfly pulled tight (like its supposed to I believe).
