SAAB 900 Hatchback Louver

Hello there everyone and good morning. I am a huge SAAB fan and my family are working with SAAB as mechanics since 11 years, my father is an amazing man and he has always wanted for 12 years now to have the rear window louver for SAAB 900 Hatchback. He has birthday soon and i want to make it the most special day for him ever by making the louver by myself. I looked everywhere on the Internet but i can't find the dimensions of every part of the louver. I know that this might be too much to ask for but please can you help me and if someone knows/has the dimensions can be so kind to send them to me. It would be amazing and i would be so thankful. Thanks in advance ! Cheers everyone !
