PST Front End Rebuild for '68 A-body with '73+ Disc Brakes?

Howdy all, due to school and work it's been a while since I've shown my face around here. But I'm alive!

I just have a quick question about the front end rebuild kit from PST. I've heard wonderful things about their products and am aware of the discount we get through the forums (thank you PST!). I'm trying to figure out a front end upgrade package for my 1968 Barracuda notchback. It's originally and currently a 10" front drum, manual steering V8 car with no sway bar. I have a set of front disc brakes, spindles, and upper control arms off of a '74 Dart Sport, which has the bigger upper balljoint. What does this mean as far as ordering a front end kit from PST? Will a 1973+ kit work, or do I have to specify that it's a '68 with 73+ brakes? I just want to make sure I get the right parts for the job.
