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

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.
Mopar Action did a write-up on this a couple issues ago.
IIRC, Ehrenberg used later style right angle end links from a Ford pickup. I think he shortened the actual links and they ended up pretty short. Not much more than drilling a hole in the front LCA with a nut on the inside.
