Looking for guidance on places that might have replacement parts for the 3500 MLG; specifically wheels and associated bearings. Old system and hard to find these days.

Have you tried EDO yet? http://www.kenmoreairharbor.com/edo-floats.html

There's also Eddie Peck https://peckaero.ca

THANKS for the lead on Peck. I tried Kenmore and no luck.

Eddie Peck and Doug Ronan.

The wheels on mine are Cleveland’s and the bearings are Timkin, you can get them at NAPA.
