I hope I'm ok here...

 I didn't realize that at some point I accidentally selected 1974 Cuda 360, my car is a 73 Cuda 340, I believe most of the changes happened for the 73 year +?

Am my hosed here for fitment or am I okay on this?
Same ball joint fitment from 73 to 74?

My main concern.   ^^^^

I'm starting to actually regret not going with the Moog lower ball joints, but I haven't really heard anything good or bad about Quick Steer (Federal Mogul)

But they had the same part numbers, so I went the Quick Steer route.

Yep your good, same ball joints 70-74 E-Body

Thanks for the reassurance, I just realized I can go back on the website and double-check that the same part numbers versus year..

Wheeeaaauuuuuuu....   😁

Yea...I usually stick with all one brand, Moog all around. 
It's hard to beat $13 for a lower ball joint

Sorry, no experience with FM lately. Just check them after a few months I suppose.
