PRO485 clamp help
 

So I picked up a pair of used 485s but it has the old style square clamps for a 3" tower. My tower is 1.75" so needless to say it wont work. I called wetsounds and they dont have the inserts for that type of clamp anymore so I was wondering if anyone has any inserts laying around or maybe even the whole clamp. I would hate to have to drop another $400 just on clamps...

Thanks!
