i how do people finish off the joint at the front between skuttle and the bottom of the windscreen? cheers ben

I think in the book he just chucks a strip of rubber (prob with silkaflex?) underneath the bottom aluminium rail, as far as I'm aware it just rests on top of the scuttle and is bolted at the sides through the triangular supports.

I have "t" section trim slid into the bottom rail of the windscreen

Yup, T section is what you want. I got mine from woollies.

GBS (Great British Sportscars) has it too.
