Raised spindles and wedge balljoints, Someone explain the difference in balljoints and struts Options

[stugray]

I currently have my car lowered for racing.
Brant tells me that I will likely blow out a shock because I have almost zero travel left.

I also need to add another ~1 degree of camber for the Hoosiers.

So I want to buy the Elephant Racing offset (decambered) balljoints:

They take the wedge bolt style of fastener.
My car is a 71 so I assume that I have early spindles.
One side of my car has the round bolt holding the balljoint in, the other side has the wedge bolt.
The PO must have replaced just one balljoint.

So if I want to install these balljoints on an early spindle, will that be a problem?

And if I want raised spindles, would I be better off buying a set of late spindles to raise?

I also learned that you can swap early versus late rotors, but you have to swap the calipers with them.
So I currently have late rotors and calipers on the early strut/spindles.

bdstone already gave me some advice but I figured I should some get some thoughts from others who have done this already.

And does anyone have a set of late lowered spindles for sale?
