I certainly hope someone here can help you.
I Purchased a Roadster this year in the spring and dread running into problems such as yours.
Of course most know I had a Coupe for 11 years.
During that time I rarely read or paid much attention to the problems in the threads that Roadster owners had thinking I have a Coupe and I don't need to worry about that
I pay much more attention to threads now regarding Roadsters
