(link is for A15 manifold and carbs - but they have brand new 48 and others just give them a call)

You can pick up a twin Webber set and also manifold from them.. or single carb

I got my twin 45mm Webbers and redline manifold for my A15 from them.. great guys with some awesome help, they will also tune the carbies to your engine specs if you provide them to them..

I had mine tuned and sent, bolted on with no issues and runs a treat starts cold no choke most days
