Yeah but you get what you pay for. Should at least look at an aftermarket housing. They are cheap enough, and not nearly as prone to bending when brackets or trussing is welded in.
Low pinion 9's are hard on driveline angles, and prone to getting beat up a lot. I'd recommend a pinion gaurd as a minimum.
Stock 3rds have a tendancy to crack and or rip apart. I wouldnt do one if you are doing anything more then beadlocked 35's.
Unless you re drill the shafts and do an 8.8 brake conversion you are looking at currie shafts and an aftermarket brake kit, which might get spendy.
If you want cheapest there is jeep to jeep swap with reasonable strength, the 8.8 is the axle. It will be close to the strength of a stock 9, and a lot cheaper and easier to swap to a jeep.
Even getting fancy with a spool, super 88 kit, and new gears and bearings you are into an 8.8 for less then 2k if you are doing it all yourself.
Or for 1500 more you can do a spooled tru hi 9 with 40 spline semi floats, custom width, bolt pattern of choice, and 8.8 disks.
Clayton at evolution has the jig tool for welding currie big bearing 9" ends onto bare housings.
