Agree with Dwayne,
on my 68 I have the RRS- struts with their phase 3 brakes (13 inch with 2 piston calipers)
Plus the RRS rack and Pinion.
The suspension is good.
Brakes where better when I swapped pads to a good set of Bendix Pads
Turning circle with the rack and pinion is slightly worse but nothing to worry about. Benefits of directness and no slop is far worth it, but if its perceived as an issue you can run the standard drag link , tie rod ends up to the RRS strut suspension.
