1968 10" drum brake hardware kits?

I did just find some (well, maybe, if they actually have them in stock), but they're for a later car (1975 spec), but 10" rear drums. It doesn't say width though. If I go tomorrow and they are 10x1-3/4", will they work on the '68?

Sorry for all the questions, and thanks for the help.

EDIT: DOH, just saw your reply on BBP, forgot about that.
