New O2 sensor is too small, help needed, URGENT

[mark241307]

The parts guy gave me the wrong o2 sensor for my 2000 frontier 4x4 5sp. 3.3L. Their computer said about 10 different bosch o2 sencors and they are all too small. The thread on my old sensor is much bigger and all the ones they say are for my truck are all the same size. My sensor is a Bosch LSH 24- 0 258 055 861/862, I also have one that reads 0 258 005 102/103. The part number is not on the old sensor so I cant get a cross reff for a new part. I cant find the cross reff for these types online either. Does anyone know if there is a substitute for my sensor or what the Bosch part number I need is? Or is there a double thread spacer I can put over the parts that dont work? This is very important and I would appreciate any help. Has anyone else had this problem?

It'll cost more, but I;d strongly consider going with an OEM sensor from the dealer.
