A little FYI for anyone wanting cut down a ZR2 rear end . The measurement for housing flange face to axle face is 3.5 " and I'm now being told by the company that I ordered my axles from that they can't make axles with a 3.5" hang out . So I'm going to take my stock axles in and see if they can be cut down (I hope) What I have right now is a ZR2 rear end cut down with all the brackets welded in place and ready to bolt into my TCI 4 link and it may be junk . Oh well lesson learned and I'm not naming the company I'm dealing with because they have a great reputation and it's really not their fault.
