got it solved- I had to grind the heck out of the holster cup. took off probably 3/8" of material. I would grind some, fit it and see where it was scrapping still, grind that area, re-fit, grind, re-fit. Took about 2 hours of this process.
I wrote RC and let them know, after looking at the A-arm design I noticed that the back side of the bushing area was thicker than the front side which the arm welds onto. The could readily fix the grinding fitment issue by a simple re-design of the bushing housing making the back thin like the front.
Ive had 3 trucks now, miss my Tundra, my Tacoma was just a monster (7" of lift, supercharged on 35" tires) and now my Titan. I had my tundra leveled as well and I have to say this RC kit with the arms was much more difficult for a home garage mechanic to install, but results were far better. I used the RC leveling kit on my Tundra.
Now to get it aligned- I like my alignments to have a slight negative camber so the tires sit more flush rather than wearing on the outside as the typiclly do.
