Solihull? That is not a location - note how I put "Fort Worth, Texas" to make it clear where I am.

If you are in the UK or EU, I don't know of anyone. If you are here in the USA, we have several people scattered around the country that can reglue the window (it won't last but if you insist on trying and throwing $200-$400 away....) or that can replace the top for no more than $300 labor. The top is currently running $800USD, delivered in the USA.

Your top is close to 20 years old - it is time for a new one - I glued mine four times and had enough.
