I'm about to order an airbag kit, but am unsure which company to order from. I think I've narrowed it down to either FBI or MIC. Anyone out there have any personal experiences/preferences on the two? Also, besides the kit, what else do I need to lay frame? There are a few things that I know I need. Lowered spindles, 4-Link, depending on if the kit comes with the c-notch I will need one of those. I've also heard about the transmission crossmember getting in the way. Is this true on a 96 GMC Sonoma ext cab? What about the crossmember for the drive shaft that holds the carrier bearing? Do I need to take out my wheel wheels to lay out on 18"s with low profile tires or does each application differ? I can get stainless steel 3/8" line. Is it hard or worth it to run it? I know these are a lot of questions, but I want to do it right the first time, and instead of asking one person that is out to make money, I'd rather ask fellow enthusiasts. Thanks.
