I've got a 12=14 year old Grizzly G1019Z BS and it uses the round guide blocks. Well those are getting harder to find and I want to convert to using the 1/2 x 1/2 cool blocks, NOT rollers. To do this I need to replace both the upper and lower guide block support. I know a number of parts from the Jet 14" saws work on my Grizzly. Could someone measure the guide block support shaft for me and let me know your model number. I can find Jet parts but Grizzly only has the parts for the round guide blocks. The rectangular shaft measurements should come out to something like 3/8w x 5/8h x 2L. It's just the part the holds the guide blocks.

Or if someone has done this before and has a different parts swap, please let me know. Thanks...
