Which Carburettor for a 407 ??

[mustdav]

I am trying to get my 407 MOT'd but have found problems with the Holley carb and cannot obtain the spare part needeed so am about to purchase a new carb.
Gregg said that it is not the correct carb for the car anyway and that I should buy an Edelbrock rather than the Holley street avaenger that was mentioned in previous threads.

Pls advise which carb, authenticity is not high on my priorities but reliability & access to spares are together with ease of fitting.
