Catalytic converter/Lambda sensor selection

Hi all,

Where better to ask a van question than a bike forum! Actually I already tried the van forum but no one answered 🙁

A couple of months ago the catalytic converter and Lambda sensor connected to it was stolen from my Suzuki Carry van (year 2000, G13BB engine). I am now trying to get replacement parts as the garage I normally used were not able to source them.

I think I know which catalytic converter I need but selecting the Lambda sensor to screw into it seems to be minefield. It is just a little thing but needs to be right obviously. I am no car/van expert but my understanding is that there are two lambda sensors; one just after the engine and another in the catalytic converter itself - which is the one I need.

I have asked some advice from suppliers and received a link to this list I am not sure if they are all meant to work for my purpose as some seem to be 'before catalytic converter' so may not work where I need it.

I might be a bit hopeful but I want to buy the right one first time! Any advice appreciated.
