Replacement Soft Top / Hood Reconditioning - Scotland

[BurblingBrownOne]

Has anyone any recommendations for Soft Top Frame reconditioning / replacement hood fitting in Scotland?
Looking to repair / renew Softop for Triumph Stag and due to variations in 70's British automobile manufacturing assume its best to get a new frame / hood fitted to the actual car itself to ensure it actually fits, opens / closes as required.
Rather than purchasing a standard sized replacement and struggling to make it fit the actual car.

Any recommendations or hints / tips gratefully appreciated.
