I know I could take the upper arm cross bars off and grind down the spacer/back of the cross arm, but that will leave no room for any alignment adjustments at all. Just looking for some advice on what to do - I still need to get a good pic of the positive camber but it's obvious just from eyeballing it on the ground.

As mentioned, the arms are basically the same (both upper & lowers). The bushings were different & the BJ sizes vary depending on size/weight of the chassis (1/2 ton vs 3/4 & 1-ton).
I have OE stamped steel 63-72 1/2 ton upper arms (w/1-ton BJs) on my CC Squarebody dually. It had the stock lowers & now has Porterbuilt 1" Forward aftermarket lowers.

Hopefully you can that pic & post it so we can get a better idea of what you're up against.
