What are the advantages of swapping the crossmember to 73-87 unit (ground clearance, better geometry, ...)?
Is it in some way better then 63-66 crossmember?

I have some options on some available parts. I already have upper and lower control arms, rotors and calipers in a box from the PO, though I don't know what year they are from yet. I might get some tubular upper control arms to correct some of the geometry and I'll be using dropped spindles and springs. So if the only advantage to the 73-87 crossmember is that it already has everything bolted to it and can be installed as a unit I'd probably be better off just switching out parts.
