Don't know where I found the information, but Grizzly has guide block holders which allow using guide blocks on a G0555. If this was posted here, sorry to repost, but I figure somebody else might want to do the switch.
Part is P109005A, Guide Block Holder. You need to order, or have on hand, a set of screws, M6-1 x 10, as the holder comes without screws, Part number PSS01M. This setup was for another Grizz bandsaw, no longer offered, so who knows how long these will be available.
With a small amount of file work the set up accepted ceramic guides and thrust "bearings", and, in my case, will save replacing the bearings when I resaw wet cedar for my wishing well and out house projects.
