Just did this about 4 months ago. (repeat all of above)
I went ahead and replaced the shoes, hardware, and machined the drums during the cylinder job. Might as well, since your there all ready. Also, you might look at replacing all your hardware, depending on what shape your current hardware is in. OGTS has all.
If you shear off the bolts that hold the cylinder to the shroud, you can go to a VW shop for a replacement. They have Allen bolts for VW's that work the same, only you can get a better grip on them.
I found that out the hard way.
