Part # for trans vac hard line pls

[Mrturner1]

Well I just recently figured out that for our trucks equipped with a th400, you can't use a rubber hose for the vacuum modulator line to the intake manifold....woops.

Anybody have a part # for one they have actually used? I don't wanna get any of the 100 different peices I've seen by googling it, they all have terrible reviews with people saying its a waste of money and certainly NOT application specific

Thanks guys
Matt
