Thank you for your help cooljess76 and spidertri. Im 100%ly dedicated to this job. I saw some manuals about the top but they are not clearly showing the procedure of removing the parts. So i will be challenged by it.
All my work so far was just to know what was going on on the inside. All the measurement details will be posted with better pictures next weekend, hopefully
Additionally, i bought the rims spidertri. They werent that much bad.
