Choosing the kit for Cobra 289 build

[martin155]

Hi,
I decided to build the 289 Cobra (no racing model..just basic steering, brakes, suspension and 302 engine) and if possible I would like the period correct car interior and exterior. I was hoping to fit in 35K but that won't be probably possible because of the customs fee (I am from Europe).
There are some companies in Europe also but I am not sure about them. Is there by any change somebody who has experience with http://pilgrim-motorsports.co.uk/ or http://hawkcars.co.uk/ (or any other) in comparison to FFR/ERA/Superformance?

Edit: If I go with FFR could you please advice me where to get authentic interior and exterior parts?

Thank you very much.
