That sounds like progress! There's something really cool about having parts show up. I get excited like a 12 year old at Christmas when i get a delivery!
I was going to get a used floor hump but a local guy has one for 100. bucks and it has some rust on it and a chunk of floor attached and was torched out so its probably warped.....its ugly and a mess.
40 dollars more gets a brand new AMD hump from ebay....ready to weld in and it straight and ....well, NEW.
I figured, why fight it and just went new. From experience they fit really good because I have an AMD floor hump in my 68 dart when I put the OD 833 in.
