Glenn,
I'm finding the same issue as you are. I purchased a complete front crossmember and really dropped the ball!! I didn't ask the guy what year truck this crossmember came off of! I ASSumed they were all the same!
My truck is a 1972 and the brake hose connection is on the front side of the crossmember, and the one I bought is on the back side. (I kept the old one for reference)
The hoses came with the assembly but weren't connected to anything when I picked it up. Only when I went clear through the assembly and attempted to connect the lines did I see the difference.
I haven't made the change yet, but the plan is to cut the existing brackets off of each crossmember, and bolt the ones off my original crossmember to my new one.
The plan is to do this swap this weekend... I'll check back and see what you came up with for a workaround and hopefully have pictures to share.
