Del Mar T Shape Rollers

Hello- looking to find a replacement for (10) roller assemblies for (5) of our sliding glass doors. They are from the late 70's so I know Del Mar discontinued the T shape. Below are photos of the old one.

I have found T shapes by slide-co that fit perfectly but they are missing the side screw hole to tighten them in place. Before I get out my drill I thought you might have some advice.

Thank you,
Sean
