Ideally, two or three people could orchestrate to buy one of each then compare with photos and measurements. Just to put any questions to bed. I doubt that one of them would get stuck with a junk manifold, so there should be very little to no risk. While I am very confident of that, don't take my word for it.
Like my pal AirQuez has mentioned on here, Miragers are poor and lazy, otherwise I'd have them compare. Plus, our cars came with them so there's no need for us to buy one.
