Not sure what you mean by center section. I actually won't be able to sell it though. I have to put a new ring and pinion in it, because it was previously set up wrong, and the spider gears are also trashed in the posi. I'm putting in a wave track posi, and Yukon gears though. Whoever said working on a 9" is easy and cheap is crazy! I would say after what I've gone through with this rear end buying it used just buy new! It will save you a lot of time and aggravation.
