I have a 3.55 8 3/4 rear end that I want to know if it is a one wheel peel or a posi? I can not see any clutches but I am not sure what it is!

you just made my day, thanks! It looks a lot different from my 3.23 one wheel peel so I was not sure and my 3.91 you can see the springs and clutches in it!

The one in this picture you posted, is considered by many, (including myself) to be the better unit over the cone and cup style where you see the springs.

I am just learning about Mopar's, I have always had Chevy's in the past! thanks, what get's me is, I have no idea where I got this from but it will be the replacement for my 4.10
It's actually a Spicer power lok and it is the best posi out there, the more power you put to it the harder it pushes on the clutches, all the parts are available to rebuild it if it needs it. I have rebuilt many of them.
One more “posi” outta youse guys and you’re all going to Suregrip Jail!!

where can I find that service manual?
I found it online for free, I'm sure it's still out there, That one is for the Dana 60 and they are the same, the 60 has bigger bolts so the torque specs will be different for the 8.75. Get a factory manual from 69 and back I'm sure it's in there.

When you rebuilt those clutch SG's, how far gone were the clutches? Only thing I think of when rebuilding a SG is the serviceable bearings/races and those are the same, SG or peg-leg.
The clutches are all steel no fiber on them from the factory, so what happens the clutches start galling, start peeling up metal then they don't have any surface area so they slip. The manual just tells you how to put it together, there are several ways to put in the clutches.
here is a link to the manual. http://media.spicerparts.com/cfs/files/media/ahd5WcQ3TvJismpvQ/5315-3.pdf?store=original
