The only trick bag you get into is if you don't want to use a camber plate and want to use the stock upper mount (as I do). Because camber plates are an easy-button for anybody doing track anyway, nobody has bothered to make a part to adapt a flat, hard mating surface to accept the swifts etc., but I think it'd be relatively easy to print a polymer adapter and then cut a small piece of sheet stock to protect the polymer from metal wearing through it.

I might fiddle with it once I get my rearend setup sorted.
