Which Supplier for Auto to manual conversion

[uk68327]

Looking to pull the trigger on a T56 Magnum for my 1st Gen Camaro.

Apart from Hurst Driveline Conversions (who's website seems to ignore my request for a quote - twice), who are the top companies that will be able to supply me with a complete conversion from an auto to manual (without the driveshaft as I can get one made in the UK).

I'm thinking of Frank @ Prodigy as a definite candidate

Thanks,
Mark
