Had to remove the bottom piece from the door and knock out the existing rollers from either end. Measurements seem to be about 3" x 1" (maybe a bit more plubs 1/16") x 11/16"

Hello, thank you for posting,

Please start by reviewing the style of the 81-049 roller assembly. Compare the overall dimensions below to determine a good fit! Let us know what you think and if you have any additional questions.

The roller has a 1-1/2" wheel, if yours is 1-1/4", you may need to replace with the 81-266 roller and axle kit.

81-049 is too deep (1 3/16") to fit into the 1" track - see pic

Unfortunately we do not carry a housing with the dimensions provided. Our best option would be to replace the wheel and reuse your original housing if still in good shape. I apologize for the inconvenience. Please let us know if you have any additional questions.
