What fits, late to early front end parts to swap?

Regarding the sway bar, first off, you'd have to have some good fabrication skills to find a way to support the bar and mount it since the 73-76 sway bars go through the K members in stock form. IF you could build mounts for it, another issue exists....The early A body frame rails are closer together than the 67-76 models. With that in mind, that means that the '74 sway bar ends will be an inch too wide on each side if you can build the mounts to secure it. You'd be better off buying an Addco front bar and use their 90 degree brackets that attach to the shock bolt.
The lower control arms with the sway bar brackets are desirable and would sell quickly.

the 73~76 bar pickups are at about the middle of the arm, so i don't think width would be an issue, it would just put that end link pick up further out like on the 67~72. although the bar does pass thru the K it's relatively straight-ish, so i think with some creative shimming and flat stock you could probably reuse the stock mounts. basically, all you would need to do is fab up some tabs.

i guess it comes down to spending 300-ish bucks or an afternoon with a 12 pack and some fab work.
