Technical 51 Cadillac A/c bracket

I have a bracket like the attached picture. I cannot for the life of me figure out where and how it bolts up. Anyone have a picture or some insight. Motor is a 331

Thanks

 

good luck....the bracket hides where you can't really see it....and this one might be a differentyear. It has the later AC compressor mounted to it, also.

 

Thanks. I can see the bracket. What year is the motor in the pic?

 

I think it's 55.

 

Anyone?

 

As far as I know factory A/C wasn’t available on 1951 Cadillacs. It may be for a ‘53 when A/C became available as an option.
Maybe an old parts book would show it.
