New roof for a 996 convertible?

[mak]

My rear screen has seen better days and it seems to have come away inside from one corner ( the plastic moulding clip thing) causing it to be a little slack and unsightly.
Can any one recommend a firm that can replace my screen and moor importantly make a good job.
There seems to be a firm near me ( derbyshire) that advertises a complete new roof with rear glass fitted for a £1000 although they do state its for a boxster ( is it the same ish).
