Well,
I finally got my Mustang II 8" rear bolted in. Yes it was a pretty easy swap. I noticed that it pushed my driveshaft a little farther into my T5, but still has about 1/2" to 3/4" clearance, and doesn't touch the tail housing of the trans. I filled it up with gear oil, fired it up and this thing sings a high pitched whine, louder and higher as the rpm's increase. The only thing I did to this rear was change the pinion seal and was careful not to overtighten the pinion nut (which was not very tight when I took it off). Have any of you had a singing rear like this. It kinda goes SSHHEEEEEEEEE and when you let it slow back down it's like a SSHHeeeeowwwww . Pinion bearing worn out? Obviously the rear was used, so I had no idea if it had any problems or what kind of mileage is on it. I need to have this thing up and running for Knotts in April.

I'm pulling the third member today and having it rebuilt. The guy says it shouldn't be too bad. I definitely wasn't going to run it anymore until it was fixed. I didn't want metal parts flying around in there!!
