Thanks for the picture!

The closest replacement we have for your Monarch 5129 Lights on your trailer is the Triple LED # CE44VR. This light measures 14" x 6-7/8" so it should completely cover your old mounting holes, though it's going to take some work and DIYing to get this fit. I'd make sure to seal all the way around the light with some non-sag sealant # AL63KV that way you don't get any water inside of your trailer.

In the picture of the Monarch 5129 Rob was asking about there is a license plate holder which is a Monarch 8004. I need that exact part for my 1977 Fleetwing. Do you have anything like that?

@Scott No sir. Monarch stuff is long since been discontinued. If your only option is that exact part, some sort of RV resale place/RV salvage yard's gonna be your only choice.
