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

Everything control arms out fits fine and will work. Use the '74 proportioning valve and a dual master cylinder from the same.

As for the sway bar. The '74 control arm tabs will not work with the '74 sway bar, BUT I have held a '74 bar up to an early A and the width appears to be ok IF you fab up some k-frame brackets and put sway bar tabs where they should be for that width bar.

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.
