The evaporator install instructions says to stretch the duct material out. On my install, the air plenum has (4) 2.5" connections for ducts to connect to, 3 of the 4 ducts will need to be bent beyond 120 deg. to get them routed to the dash vents. How do you stretch the duct without causing it to kink or turn a hard right angle where it attaches to the evaporator plenum. It would seem to me a hard turn would cause a restriction in air flow through those 3 ducts.


I'm looking for guidance from someone who has done this before me. What was your solution or am I just being ****?



Thanks

I have never installed these into 67's but have done many street rod installations. The ductwork tubing has a stiff rib in it that prevents collaps when bending. As long as the connecting material isn't split, the round tube should be ok when bending. I have had to bend this stuff 180 degres and never had a problem.

I haven't "done it before you" so I guess you won't be interested in my reply, but I would lay the ducts out in the sun for a couple hours to make them more pliable.
