1. Nobody makes a 4wd conversion kit but man i wish they did, i wouldn't have to drive to missouri (5 hours) just to get a k30 frame.

2. That k25 should have a 14 bolt rear axle, which are VERY VERY hard pressed to destroy, if not impossible. I broke one only by flipping the truck and it just cracked the axle tubes. The front should be a 10 bolt, strong up to 38's or so... A 1 ton dana 60 will give you more strength but woo they're expensive.

3. None of my trucks had AC so good luck!
