833OD rebuild Qs

Yikes, The carnage in there looks scary. I do have a fair amount of patients

I plan on getting:
RBK10 - BEARING & SEAL REBUILD KIT 1980-87 TRUCK
SR307 SYNCHRONIZER STOP RINGS LATE 1970-UP LUG STYLE

Does that seem like all of the parts I'll need? Should I get the synchronizer keys just in case or is that overkill? Sure as crap don't want to tear it apart twice.

Well, I suppose I'll pull the cover to see what I can see....
