Assuming you’ve already stripped most of the parts?
Should be one allen head bolt top and bottom of the shock, and I think the bearings come apart with just one preload bolt and one pinch bolt IIRC?
You’ll also need something to drift the headset out with (a flat screwdriver inserted through the headtube and hammer and work around slowly works well if you don’t have the tool). Bottom bracket will need to come out too (likely a standard hollowtech style spanner).
Remember to point out all the bearing surfaces and threaded holes to the powder coaters, otherwise they’ll come back full of paint and nothing will fit. And make sure they go easy and use a soft abrasive, sand blasting will probably take half the aluminum away with the paint!
