Just sayin, in my case, my engine is offset 1" to the pass side of the truck. Dont know if the LS engine is the same.
Anyway, my point was that if a two piece is required use a really strong center bearing, pillow block, or flanged bearings can hold extreme amounts of pressure. I built a "Drive Unit" to take to a professional to duplicate with new parts, and balanced.
Stock stuff is just that.
