Hi
Does anybody know if a Westfield sei wide screen will fit my GTS

I don't know the answer to your specific question but I do know screens don't need to be an exact fit. I used a Caterham screen on my Indy and Caterhams are quite a bit smaller, and a slightly different profile on the scuttle.

The rubber trim on the screen takes up the gap.

I think Westfield use a fillet at the bottom of the screen so maybe you would need to make something to replicate this or adapt a Westy fillet.

Assuming you can do that, as long as the width is about right there is a good chance it can be made to fit.

Have had 2 screens.

1: Westie wide version. Did not conform to MK scuttle profile. Definite no-no.

2: Caterham screen frame (no glass), unknown vintage, but more than 12 years old. Fits MK scuttle OK.
