PST Kit for 71 Dart

Hi all

Our local shop is installing my new Power front disc brake conversion kit on my 71 dart and I will need to replace the upper control arms due to wear. Any idea what size lower ball joints they send with this kit? Larger or smaller? I'm liking the QA1's. But seeing the 52303's are for small ball joints, and the 52301's are for the larger ball joints with disc brakes, 73' and on.

Any help would be great. Thanks!

I don't have that answer, but keep in mind there are adapters if you have to use them.
