A-Body Frame/Body Jig
If you only need one frame rail, you really aren't doing yourself any favors by replacing the entire front clip, unless there are other problems. Either way, lots of people replace entire front clips without using jigs. Many examples of this being done with nothing more than a flat floor and jack stands.
Two YT folks come to mind immediately
SWRNC - He's abrasive but he shows replacing a front clip on a mustang, the process would be almost identical to an A body.
Joe Daddy's Garage. - Actually rebuilds a mustang convertible using DynaCorn parts and the original "vert" parts, etc.
Actually, there is also a guy who rebuilds a 70 AAR cuda on jack stands.
My point is, you don't "need" a jig to replace a front clip.
Full disclosure, I built one for my 70 cuda vert because by the I am done, probably 80 percent of the car will be new. (rust bucket from hell).
If you Do build one, don't overthink it. It's basically a short box with 8 pedestals. On my cude, the middle 4 are all the same height.
Here are a couple of other examples..

This is my jig. I threw together removable castor mounts.
