front end rebuild suggestions needed

I'm going to swap the /6 torsion bars in the son's Duster over Christmas break, and just looking for suggestions on what else to replace while we're at it, and whether to go with poly or rubber components?

It's a 70 Duster with a 318/904 drivetrain with the 7 1/4 rear still. It's been upgraded to front discs from a 75 Dart, and upper and lower ball joints are new from that upgrade this summer. Going with Just Suspension's 1.00 bars since it's almost entirely street driven and might see a strip once a year.

I'm thinking it would be a good time for LCA and UCA bushings and strut bushings, but can't decide whether stock rubber or poly replacements, and is there anything else to replace while we have it apart?

Thanks,
Scott
