Carburetor replacement questions..

["Wil Boucher" <william@imag.net>]

Hi List.

Got a question about carbs for a 69 MGB. I have access to an set of  AUD 135
and a set of AUD 405 that are NOS, currently on the car I have AUD 326's on
their last legs. The questions are; what sort of problems would I be facing
if I tried to replace the 326's with the 135's or 405's? Which would be a
closer match? Risks?

Thanks in advance.
