Phil, I did the front end of my '69 about 6 years ago. I used the PST "Polygrahite" master kit. I did it while converting over to disc brakes. I also used a PST 1 1/4" front swaybar.
I also did the rear suspension at the same time. I added boxed lower arms w/ poly bushings and a repro sway bar.
Both front and rear got new Moog springs and cheapo Gabriel low pressure gas shocks.

I've been very happy with the set-up but then my driving is a little more agressive than yours.

If you're going to put on 14" redlines you may as well keep it stock as you won't be able to really take advantage of the aftermarket stuff. If you do 16"+ the suspension improvements will be much more apparent. Keep in mind though, a '67 convertible is pretty flexible so it's never gonna be a canyon carver.
