How was the install? Heard it's almost impossible on jackstands.
Well, if I had to do it again, it would take 1/3 the time.

If only jack stands, maybe but certainly more difficult.

Two tips:
1. Left side install all top bolts approx 1/2 way, then Header, then bottom bolts. But the bottom closest to back of car doesn't fit unless all bolts are loose. (or grind 1/4 in off top of bolt).

2. Right side install top middle 2 bolts first 1/2 way, then Header. Then rest of bolts.

Need super long 11mm wrench plus all the tools suggested in this post.

Did you get them already coated from Kooks or send them off?
