It's in
 

The 12 bolt is in ,my son & my friend Harry helped me install the rear .Also thanks Slowhawk & Jay Fisher pontiac for the tech support.Strange was closed today & you guys answered my questions.

awesome. so you got a strange rear with 4.10 gears?
when are you going to race with it? you have sticky tires?
is your clutch up to the task? which clutch you got?
any gear whine? if not now, you may get it (probably will) after a few hard launches at the track with slicks.
what did you set pinion angle at?

I went with strange (took 4 weeks)and got 411 gears.I have bf goodrich drag radials and a specIII clutch.I set the pinion angle @-1.I have not drove it yet because of the rain and I broke the wheel speed sensor on the passenger side during the install.Hopefully I'll get the the part today and I can drive it Wednesday. Strange suggested drive 50 miles and let it cool down.Then I 'am good to go.
