I rebuilt both my lowers a few yrs ago. Made the tools myself after getting the dim. from the merc tools. The merc tools can be rediculously priced. for the 1 time use. Also had the Merc manual. Has everything in there you need to know.
This place has the drive tools;

Just a couple of the tools I made, bearing race installer for setting depth, backlash, shimming , large nut installer. A few others I don't have pics of, but at a cost of $0, just my time.
