Which Lambda sensor + sleeves

[Tommyboy1507]

Right I've just had a mk1 raceland 4-2-1 manifold fitted to my mk2 vtr. I've tried looking but I just want to know is it the top green lambda sensor or the bottom blue lambda sensor I fit into the new manifold?
Also do anyone know where to get a cheap lambda sleeve, cheapest I've seen is £18

Its the upstream sensor you put into the manifold (the one before the cat)

The downstream one has the sleeve on.
