Automatic gear box conversion

I'm thinking of swapping out  my 3 speed BW35 automatics transmission for a 4spped ZF4 one in my Triumph. I have been given some instructions on what to do. The end of the torque convertor needs to be machined so it fits in the end of the crank shaft. Does anyone know of a place? The torque converter is heavy.
