If you get the tubular A arms, they're already offset so you don't need the offset bushings. As far as kits go, it's hard to tell what the quality is today. When I rebuilt my front end I used a combination of vendor kits and Moog pieces.
If you're gonna beef up the suspension, I suggest adding more than the above kit. As others already mentioned, unless you're going for a stock look, go with the solid tie rod adjusters with the larger tie rod ends. What about the pitman and idler arms? Since the LCA's have to come out, might as well blast and paint 'em, install new bushings (I had a shop do it). And while they're out, if you weld or know someone who does, PST sells LCA stiffening plates. Check out your strut rods for straightness, install new strut rod bushings. With the LCA's out, the torsion bars are just hanging there - what size are they? If they're .92's you might want to think about going up to .96, or even the 1.03's from PST. With the front end apart, its a good time to upgrade shocks if needed. A lot of members like the KYBs, I prefer Bilsteins.
I did all of the above on the Coronet and had the p/s box rebuilt by Firm Feel and the difference is amazing. The car handles better than newer full size models. I dug it so much, then next year I duplicated the rebuild in the Dart (manual box). Now I can throw that car into corners and the limiting factor is tire rub in the back.
Doing some or all of the above will set you back some more coin and a few more weeks waiting on parts, etc. But IMHO its worth it.
