We have several WW2 Jeeps running with Weber Carb conversions.
The one we use was originally made to use on the Series 3 Land Rover, which is conveniently 2 1/4 litres -the same as an MB/GPW.
It is Weber model 34 ICH
The modifications to make it fit are very easy.
The mounting holes need filing out a fraction to fit the Jeep studs.
I used a gasket rather than the Jeep wartime atomiser
The butterfly lever needs to be reversed and straightened out(as it is cranked)
There needs to be a piece of tubing of the correct size cut to join it up to the air/cleaner horn
The kit is priced in the US at about $150 and is complete with fuel hose, in-line filter ready to connect to the Jeep fuel pump.
It gives very good gas mileage and easy starting right out of the box
