this pb is then bolted to the flange with 3 bolt and the webber has to be bolted to the flange in 4 places but in places different places.
the webber also sits on this.

but im after a flange that has the webber top half, a 34dmtr and the pb bottom half, a pb 2e3. do they do them?
i think the chap had it on a a rocco?
its a 34dmtr and it says on webber.com that a 32dmtr is needed will this make a difference.
