The 2wd burb parts are the same as 2wd blazer parts, which are the same as 2wd pickup parts, at least in 1/2 ton stuff. The rear is the same as well, which you would probably want to swap, or at least the axle shafts and drums, to get the 5 lug stuff. Getting a burb will net the heavy duty brakes (1.25" rotor), and they are a dime a dozen around here. I think the swap would be worthwhile, but it may be more time consuming than anything.
