brake shoe source

Post a photo of the shoes you have and holes you are talking about. As far as I know, all drum shoes are the standard Bendix design, used on most cars. The only kink I recall is that you often need to press in a short stud (that comes in the box) as a pivot for the self-adjuster if using the later "improved" adjuster (has a spring on the cable). You can find many photos here and in the factory manual.
