I ordered both O2 sensors for my 96 T several months ago. The set I ordered showed up within 5 days. Then about a month later another set showed up and has been sitting on my shelf. If yours does not arrive by 8 weeks and you do not get a response, let me know which one you need and I will send it to you.
