Sliding hatch for V20 cuddy cabin

[axespino]

I am new to this forum and hope to help out and get plenty of help from my fellow V20'ers. I currenty have two 1973 Wellcraft V20. One which has been in the family for years which was a I/O and now has a 1989 175 evinrude with tow buned up pistons and the other which I recently purchased for $300.00. Both of these boats are missing the sliding hatch cover for the cuddy cabin roof. Does any have one for sale or have an idea on how to fab one. Any information would be helpful. I am from Palacios, Texas. Thanks.
