Change to '73 steering for header clearance?

My '72 Duster has small bolt pattern disc brakes on it as well as new Centerlines and tires. But, the old style center link comes out up rather than down. That doesn't work with the TTi headers so I'm thinking of swapping over to the '73 style center link which drops out down.

So is it possible to connect the '72 disc knuckles to the '73 steering linkage? They don't appear to be compatible but I haven't really measured it all that closely yet. Just wondering if others have mated the two or if everyone just goes ahead and converts to '73 and up stuff from knuckle to knuckle.

Anyone have some pictures of the SS/AA cars in this area? What are they running for centerlinks and knuckles and stuff like that? I looked around a bit but didn't have any luck finding parts for sale that those guys are using.
