Need help locating a part

I've tried all the "usual" places, i.e. JEGS, Paddock, JC Whitney, but cannot locate the in-line transmission filter for my 727. Did an internet search by part number (2400124) and one company came up; Tri Component in the Bronx. They unfortunately do not deal with individuals. I got the impression they supply other companies with stuff.

It was a very strange phone call and I don't know whether to be angry or just creeped out. The sales guy was pretty amused (almost condescendingly so) that I was rebuilding a car, then proceeded to ask if I was married and had kids.

At any rate, I don't look for a call back from him. Anyone know where I can get my hands on this filter?
