Looking for replacement rollers for an unbranded ~40-year old door.

A home owner from Salt Lake City, Utah says:
I'm looking for a set of replacement rollers for a door on a house I recently bought. It went through a major remodel in the 70s, so I'm assuming that this door was installed then.

I cannot find any kind of markings of any sort anywhere on the door or the rollers. No brands, no numbers or letters, no symbols - I'm shooting in the dark here!

See the attached photos for measurements.

Check out our 81-033 Acorn door roller. This might be what you want, but see how well its dimensions match yours.
