TOPIC: Gator trailer hubcaps

Hello, I saw a previous post about restoring gator trailers - I recently purchased a glasspar boat which came on a nice gator trailer - it is the tilt up type. Sadly it only had one hub cap. I know finding originals is hard so would be ok with putting an aftermarket reproduction hub cap on it - there are a lot of styles out there so hoping for some advice as to the correct type that would fit thank you.
