i've noticed several different styles of saddlebag supports for the savage (some square looking, some swept back, and some triangular.)  I was just wondering if the supports are universal or if different supports are for different styles of bags?

If you're searching online just include the search term "universal", or "adjustable" if that's what you're looking for.  Of course you could make your own or go to a junk yard.  You can get the stockers dirt cheap a the junk yard.
