72 Duster Resurrection

Still gathering up my parts list. Couple of questions.

The lower control arms are the same part from 1962 to 1976. Only difference is some have tabs welded on them for swaybars. The ones on your car will work for this swap.

Should I think about adding a sway bar because my LCAs have the mounting tabs? Is there going to be a significant difference in handling? I assume adding one makes my front end rebuild more expensive because I would need to buy the sway bar, bushings, etc. Im thinking towards the V8 future here...

When I call in to ask about a front end rebuild kit, is this the correct way to describe my setup:

-factory 1974 front disk brakes
-1972 a body
-no sway bar (maybe?)


Also, it finally dawned on me that no one sells lower ball joints by themselves. Is that because they are built into this thing:

So you have to buy these to replace LBJs? Is that just a fact of mopar life?

Thanks!
