Hey Brandon,
Yep, those are SN95 spindles, similar to the FFR deal. I like the setup. There are a few companies out there doing it but they cost a fortune. The spindle adapter allows you to change the height of the spindle so you can monkey around with roll center and big brakes are easy and cheap. I set this up to increase the track width by 1" per side to allow me to use FR500 wheels without a spacer. I am going to use a FOX rack and pinion. The base design puts the RC around 2.7", chamber gain of 1.1 deg per inch of compression, and caster of 6 degrees. I am making a couple more kits for a couple of friends so I am designed it to be somewhat modular. My friends have 66's but they are not much different. To install it, you basically slide the LH and RH tower over the frame rail, then slide the crossmember between the frame rails and weld. There are a couple plates that tie the towers in up top. I will work up some braces to go to the firewall and from tower to tower. That's pretty much it in a nut shell. Oh, I plan on using a spined sway bar up front too. I am just starting on this, but it has been a blast so far.
