I notice that in all of the parking brake diagrams, they show the equalizer lever mounting to the crossmember via an attached bracket. I don't seem to have any place to put the lever. Is the brake setup different w/ the FMX?
I don't think you could buy a new crossmember for an FMX in a '65 even if you wanted to. Whoever put that crossmember in did some cutting and welding (check out the welded mount tabs), and I think you're going to have to do the same. Weld on a bracket for the parking brake, or if you're creative maybe you can figure out how to bolt one together...
