GM made factory brackets for the 230-250-292 six. I haven't seen many on a 64 but by 66 a/c was getting more popular and a 66 has the same configuration as your 64. Maybe someone with this setup could send you a pic. I have also seen aftermarket brackets that were for the York type compressor rather than the Frigidare. Hit the swap meets and look at all the 64-66 trucks with the hood open and you might score.
