Need help with 1966 Lemans heating vacuum hoses where they go

[Nighthawk]

Hey everyone. Someone else took apart my heater core and housing and left me with a mess. From pictures I have I've figured out where 4 out the 5 vacuum hoses inside the dashboard go but cannot find where the lase hose goes to. Any help on this would be greatly appreciated. Thanks.

Do you have the 1966 factory service manual?

I do but didn't help. Found pictures of a heater box from a 67 GTO and that answered the secret where the hose went to. Now another problem. Having trouble with the transmission cable because I switched out the original power glide transmission to a 400 Turbo which changed the linkage to the opposite side. Now the original cable is too short and cannot find the correct cable to purchase.

Have you tried a cable from a 67, first year for Turbo 400?
