[70 tt rustang]

I have to make a choice on new upper control arms. My setup currently is ridetech coilovers all around with their triangular 4 link. In the front iam running global west upper, lower control arms and their strut rods. On my 1970 mustang. My issue is that the global uppers dont have enough caster built in and i cant get enough out of the strut rods, and it drives like a shopping cart. So global has a new set with 3 degrees built in, or should i go with ridetech uppers? Is one better than the other or should i keep it all global?
Thanks
