Hi - I am going to replace the four cylinder diesel in a 78 240D manual 4-speed, with a 5 cylinder diesel from an 81 300D automatic 4-speed. I am going to be hooking up the 4-speed manual with the 5 cylinder engine.
Has anyone have any advice or things to look out for.
Thanks,
Joe

Please search for "auto manual conversion".

In addition to myself, there are about a dozen others that have done it as well.
