Assuming I could find one, does anybody know whether a Bear single spring arm bow quiver, made to work with the Converta-bracket and /stabilizer bushing on post-1970's Bears , work without a converta bracket by securing the lower slotted flange directly to the riser of late 50's/early 60's Bear bows equipped with threaded quiver bushings in the side of the riser below the grip,screwing through the slot?
