My old Porter Cable 333 random orbital sander recently died (well almost). I went to pick up a replacement and discovered the new models use 8 hole disc rather than the 5 hole. Upon further investigation it seems all companies have gone to 8 holes. My problem is I've got about 300 5 hole disc that I'm not willing to just throw away.

The clerk didn't know if the 5 hole pad on my old unit would fit on a new sander and couldn't find anything in a parts manual. Has anyone else been through this with a good outcome? My other option is to fix up the old one, motor still runs but it just barely spins. The drive belt is not broken and seems in OK shape but that's as far as I went.

I don't use this sander much any more, but need to get this fixed for those few times when I need it.

Thanks, Perry
