Jimbo (see, I got the spelling right),
You are a noob, no matter how many years expderience you have wheeling Jeeps, Dodges, or Fords. You are NEW to the world of Nissan, specifically Xterra, offroading and the hastle we have with aftermarket parts. While I sympathise with you over your Calmini issue, I had to do some modification with my Skid Row rear bumper to get it mounted properly. I did the modifications only AFTER I had talked to Skid Row about it, and I had two choices, drill out some holes, or send it back, and wait another month or two for a new one...I chose to break out the drill.
So, chill out.
