really depends on how rusty the truck is that you are taking the cab off. should be pretty easy. we stuck a 2wd cab on my buddies truck and could have had it done in 1 day if it wasn't for 1 rust cab mount on the frame that he wanted to replace. did it in 2 days. i like how you get more floor space with the 2wd cab but can understand why they do what they do to the center hump, the wider hump is a bit cleaner surface to seal up around the shifter.

no problem. it is mainly the old cab and rusty bolts that might put up the biggest fight. clean cabs usually come apart super easy. unless you can take the rubber mounts out it can be a bit difficult to see what shape the mounting points are in. the area outside the where the rubber sits was fine but they area where the rubber sat on my buddies truck was thinner and the hole was a lot larger than it should have been. it would have been easy to patch up but we just replaced it since we had a complete parts truck.
