TH400 Filler Tube Problems

Hello People, sometimes the smallest things are the biggest pain in the rear :mad: ...Can someone tell me why I cant find a black dipstick/filler tube for a TH400 in my 65 chevy? I have looked high and low and the only thing I keep coming up with is a fancy $65 braided stainless blah blah or a $20 made-in-some-foreign-country chrome plated leaker that does not "bolt right up" the way it should.....junk yards claim to not have any, dealerships claim to not have any, even the local vintage chevy parts place does not have any....am I an idiot?? :confused: (rhetorical question...please refrain from answering)....all I want is an inexpensive, black (i.e. oem or equivalent), NON-leaking transmission dipstick and filler tube. I heard that th350 tubes will fit...got one from a salvage yard (free)...it does not...any suggestions are much appreciated....:CRY:
Do I just need to dig deeper in the wallet and STFU or can I get away with the cheapy ?? :confused: :CRY: ....:cool:

Thanks for your time.

The chrome ones don't leak IF you remove the chrome (grinder/wire wheel) and use a sealer with the "O" ring.

Like Charlie said. I scuff the plating up with some Scotch-Brite and load the o-ring up with some Perma-tex (non-hardening) when I install it. Never had a leak.

:D Thanks Charlie and Mark, I knew there had to be a simple solution (to my idiocy) that's why I come here...
