Had to look, not familiar with the design...

I checked the evil auction site, and see "u-groove" bearings.  Good for 
some tower systems, but maybe not for what you have.  I did a search for 
GM Hazer roller bearing, and saw the black wheel type.  Is that what you 
have?  They call it plastic, it looks like Acetal (Delrin) to me.  I've 
had a few parts made from Delrin, maybe someone can cut/turn some new 
ones for you?  I buy Delrin rod off ebay.

This link is just for an example of material, because it looks like the 
bearings on the GM site:
