I blew my 4.56 rearend to smithereens last night so I will be tearing that down this weekend, or sooner and trying to line up some parts. Something let loose and the driveshaft shifted forward and sounded like a giant metal-eating machine. I am sure it looks pretty bad inside! Puked all the gear oil out through the front seal.
I would like to find a complete 8 3/4 center section setup with either 3.91 or 3.73 gears in time to still get some Fall cruising in.
