It is from Slick Street Stuff, on the internet with photos, comes with most all the parts needed for a bolt-on type installation with rack-steering box, uppers, lowers, spindles, attachment brackets, etc. My a-arms had to be replaced because they were not the right length and steel AVCO cross shafts were only available from one parts company out west; AVCO makes many arms in aluminum cross-shafts but not steel in the size needed. You may NOT need to replace the a-arms if the kit is purchased. I originally purchased the lowered spindles and they were completely out in camber - not useable (I do not know why that was the case). Note too, I had custom brake caliper attachments made by Strange Engineering (Very nice people to work with) so I could install their disc brakes. Overall, it may be the only stock system available and seems to quite work well after mods, but I have not yet driven the car.
All this learning cost a lot of money and grey cells so if you go that route get back to me if you if you like. Steve Kramer did the work and TIG, knows this front, and I am sure would answer any questions.
If you look at the Internet picture and compare with my car, you can see the tubes and TIG largely for strengthening, fitment, and safety. I'm using QA tapered springs and QA adjustable shocks.
