the proceedure is described in detail in the factory service manual. an easier method works when the fw is neutrally balanced. which they often are. first check the fw from the engine you want to use. if it is neutrally balanced then make sure the fw you are going to use is neutral also.

also you really should swap out the radiator, speedo and rear end as well. also a second engine shock bracket must be fabricated to do it right.

and if you can do it all in a weekend i will be impressed.

did you mention shortening the driveshaft?

it is a very worth while conversion. not without effort or expense, but you get the simplicity of the 240d with excellent performance. if you do that you will need a speedo to match.

oh and i would recommend using a 346 rear end from a na 300d to ease taking off with the four speed tranny.
