i'm having a hard time picturing what you mean by "two bolts", but my best guess is that it would be best to mod the swingarm to accept the eye-to-eye shock.
EDIT: on second thought, this would be a bigger PITA, and probably less desirable, than just buying eye-to-clevis progressive shocks. however, it's just metal, so anything is possible! i'm sure someone else here has already seen/done it and will give you a real answer lol.
