as most know these plastic pieces break when replacing the top and are no longer available from BMW my best source says they will not be made .I have made a few for my customers and am looking to set up and make a run of them . I made two replacements that seem to work fine. . One is going to be easier to make and will last much longer than the plastic oem. Wonder what you guys think and if their is a market for them in the 200 dollar range .I have seen cracked and broken junk sell on ebay for 300-350
You will need to use your upper seal which I don't see going bad and the metal bolt hole inserts but they also dont go bad.

so please post some feedback as i am ready to get his one started
