I spent a few minutes on the phone this morning talking to Denny from Chassis Engineering - he was really helpful in telling me about their bolt-on kit. I asked him to fax me the instructions and two minutes later I was holding them in my hands. It seems the only hang-up would be shipping to Hawaii...he said they have distributors in the LA area (Limeworks, socal speed shop, etc) that may be able to work with me on shipping but the entire package is going to be upwards of 250 lbs.
I'll try calling RB's tomorrow to see if I can ask them about their bolt-on kit.
