Latge sliding glass door

There are 3 of these wheels on a patio sliding door from an Eichler-style house build in 1961 (unsire if the door is original).

Thanks for the help!

That's original. Joseph Eichler Loved Arcadia doors. The important dimension is the top edge to the shark fin at the bottom. You will probably have to remove the axle and replace it with one that is the same width as the original. I'll never understand why they use an axle that doesn't fit in the door.
