Our old roller assemblies from a Millard Sliding door need replacing and Luik very similar to your 81-149 rille assemblies, however, we have spacers that slide into a channel...it looks like your assembly may have a slit/spacer track to slide our spacer into?? Please confirm.
Thank you!

Yep, the 81-149 has a slit on top to let you slide the old spacer in. You should be able to reuse your old one.
