Help 5.3 a/c compressor brackets

[Longbed Larry]

Installing a vintage air in 70 with a 5.3 for friend, he wanted to use factory compressor set up and brought the mounting bracket but it doesn't look like the compressor will fit between the frame. What set ups has anyone used with this problem? Thanks for the help

I switched to the Hollley LS brackets for the AC.
