Oil filter plate leaks?

I'll just pipe up in case you do some digging and you find my previous posts on this...are you sure it is the oil filter plate?

I chased my tail on this for months
One day I decided to do a test to see where the oil was coming from and I taped a shoprag around my filter (figured if I could pinpoint the problem, maybe, just maybe I could fix it)
Went for a spin and found oil on the OUTSIDE of my shoprag
Some more testdrives with cardboard and rags in odd places led me to find a leaking rear main seal
Oil would come out at the pan, travel back and hit the torque converter. The TQ would fling it up, it would land on the filter and "bam"...highest wet spot = spot of origen, right?

My point is, are you SURE it is the filter plate?
