I finally got the 300 back from paint and now seem to have no time to work on it but I won't bore you with the details. I decided to take a job home with me and work on it in the evening. Tonight I worked to repairing the rear lens. I am happy with the results. The last one I saw sell on e-bay was sold I think for $650 for just one side and it wasn't the side I needed. I bought a piece of 3M lens repair plastic and then started cutting out the repair. Here is the before and after.
