? FM part# for FPR and O2's

[prozachappy]

Trying to replace my FPR and O2's on my 1994 2wd Explo. I'm only interested in OEM motorcraft parts, and always order from www.rockauto.com because you can usually find everything you need and their prices on OEM MotorCraft parts are usually about 1/2 the price you'll pay anywhere else. Problem is they list all these ford part# and options for a FPR for my 94. I'm pretty sure they're all going to be the same part, just succeeding numbers for parts made the following year ie..90TF, 91TF, 93TF and so on. So all should be good for 91-94 explo's right.
For the O2's...I'm not sure because there was a difference between EGR systems that were CA emissions and non CA. Mine is CA emissions with an EGR tube coming off the exhaust manifold. Not sure if that will effect which O2's I need. Plus they list one as "heated" oxygen sensor.
I really don't think it's going to matter, but I thought I'd check and see if anyone here had similiar issues.

If your familiar with FM part numbers or know what is what please help! if your just going to take a guess...don't confuse me more
thanks, Jason
