I picked the front diff up at my local salvage yard for 110 with less than 1000 miles on it.
Taking it apart was easy, took about 1/2 hour to pull it apart.Quick measurements are:
OD: 7.25 inch
ID: 4.25
43 teeth
pinion: 8 inch
I can take picks if some one can host them for me.
Install wont be for a while but I thought I would share.

 

you can email them to me.

 

Did you check the backlash spec before taking it out?

 

Never even thought about it.
I did not plan to do the install myself so it never crossed my mind. Oh well, next time.

 

here are the pics

 

Thanks for helping me out Silvers808.

 

Now it is time to install and be really really fast

 

you going to use that diff on your S?

 

f20kills,

Good job. I've got a front diff sitting in my garage as well. I do have a dial indicator, so I'll make sure to take a few good backlash readings before I remove the ring and pinion.

Chris.

 

Please do, and post back. I'd also appreciate it if you could take pics of the wear pattern...
