G1066 drum sander parts

Hey guys so I got an older grizzly g1066 24” drum sander this past week. Its not in bad shape but needs a good cleaning and re-aligning. There are a couple things I that are probably going to have to be replaced eventually…the conveyor belt being the main one, it is an older model and I know the new models come with a rubber one. The clips that hold the sandpaper on (which from what I’ve already read on here I think I may mod it in one of the ways described by others) also need replacing. Oh and the v-belts are pretty worn. Anyway for anyone who has one or looked into it you grizzly charges a pretty penny for a replacement conveyor belt. So seeing if anyone has any ideas of another choice, maybe an aftermarfet or something? Thanks for any help!
