67 Notchback disc brake/suspension questions

I got my CPP disc brake conversion kit together (im pretty sure it comes in the SBP also) with the PST greasable poly LCA bushing and mancini racing 1" strut rod with bushings. everything went together really well and made a world of difference. Suspension components were very wore out and it really tightened things up. next thing I will do is the replace the steering box with a 14:1 quick ratio steering box kit from Borgeson. Its a little more than I want to spend but ill have this car a long time so it will be worth it.

I have Hedman headers and Coy wheels. Love the wheels...

Those wheels look great, Ill be taking a page from your book and getting a set for my notch back. What size tires, wheels and backspacing did you get?
