The pre-cat O2 sensors on the BFM engine are 5-wire widebands if this is still relevant, I did mine last year. They were around £40 each (Bosch) shipped from USA, much cheaper than over here.

I think I had to remove the intake manifold. One side was fairly easy to swap but the other one was almost inaccessible. It took me a few days to finish the job in the end as I dropped my lambda socket somewhere behind the engine and couldn't find it. I think it's still in there now!
