I am looking for ideas for homebrew roller bearings, since there do not
seem to be any available with GM not selling Hazers any longer. Mine seems
to hang on R25 Z braces in a couple of spots.  Not hanging on any tower
bolts.  Anyway - any ideas?

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:
