I Have my 8 3/4 in the machine shop to get shortened, he needs the sure grip out to run a bar threw to keep it true, how hard is it to take out, never had one out before.

Just pull the center section out, sure grip, gears and all comes out. Then remove the two caps that encapsulate the bearings and the chunk will come out. I usually mark the caps so they go back on in the same orientation. Also if you plan on running the same gears, get the backlash setting of where they are now before you disassemble. You will want to get it back as close as possible. If you plan on changing the gear set then you can skip that step.
Also make sure the shop has the caps that hold the suregrip in as they will need those to clamp their bushings in.

It is very easy once you have the axles out all you have to do is unbolt the diff and pull it out.

You shouldn't need to disassemble the center chunk. As said above, just remove axles, then diff from front.
I disagree if the shop is using this method.. They will clamp bushings in the main caps in the center section and bolt it in place. Next they will slide a steel shaft through the diff, and then they will use bushings on the ends. This will ensure everything is lined up properly before welding it together.
You might give them a call to confirm this is how they are doing it.
Here is a link to the steps that I assume they are doing, this is why they want the suregrip out of the way.

Based on what I've been reading regarding shortening axles, I think the shop will want the suregrip assembly completely disassembled. I believe the shaft that they want to run through the housing passes through the carrier bearings and is used to true-up the housing ends as they are resinstalled on the axle housing after shortening. This shaft will help line the bearings up to reduce parasitic losses inherent with axle end bearings being slightly misaligned. I would recommend completely disassembling the unit so that they can use their jig and do the job right.
Now, I do not know exactly how to do that. I wish I did.
Good luck.

You beat me to it lol.
I did not even think about using bushings in the carrier bearings instead of using the center section bearings. This makes sense, though the center section could be off by a little bit (differing from the bushing used during the process you showed) and lead to the parasitic losses I mentioned.
However, there's not too much that you can do to avoid that. These things were assembled very precisely the first time around.
I agree, using the method above is probably the most accurate in my opinion. There is more than one way to do it, but I'm assuming the shop will be using the above method.
