QA1 Handling kit questions ???

Fred Scigliano- Quick question on QA1 parts used. Do you have the upper and lower control arms installed from QA1? I'm looking at one of the kits: QA1 HK12-CRA1 1967-72 Mopar A-Body Handling Suspension Kit, Level 2

They say it only fits 67-72 A-Bodies Mopars. However, I was told that the only thing required for it to work on my 74 is to use biscuit type motor mounts? I was wondering about the upper control arms from QA1. Do they use the larger ball joint? Did you have any issues there? I was planning to use factory spindle and disc brakes?
It uses the smaller ballpoint but you can get the larger one from them
