mustang 5.0 o2 sensor

[notchback11s]

i have a 88 5.0 built and i noticed that my o2 sensor are located on my long tube headers and its before the collector only on one cylinder i know this is not rite now my question is where should i put them, could i put the stock one rite after the header connect to the h pipe and put my wide band in the center of the h pipe, or what would you recommend. i have the wide band kit and moates quarter horse for tuning

I would put them before or after the flange but leave some room so you can deal with the bolts without removing the sensors. in the h for the wideband isnt a good place imo
