If you have trouble finding replacements and the originals are in good shape but just yellowed, there is a procedure to brighten them back up. You can look up Retrobright online and see what folks have been doing with it.Does anyone have a good source for replacing the A/C grills on the flybridge? They have yellowed over the years and are ready to be gone.
