I need to replace the gasket on my bow hatch. The only numbers I have is a serial number 887036825. I have contacted a few distributors and they say they need a model number. I have looked all over the hatch and can not find any other numbers. I would like to know if I have a high profile or a low profile hatch? Gasket material comes in 3/8 or 9/16 depending on profile. Please help I need to stop the leaking.
