Hi Glen,
Atwood LP detectors are phased out with only a few options still floating around out there so your best option would be to replace it with one from RV Safe. These are 4-1/4" long x 2-5/8" wide x 1/2" thick, come in black or white, are a surface mount design, and include two different trim rings to help cover up any gaps left by the old detector.
White # RS34FR
Black # RS54FR
