I have a 70 SX455 and a 72 CS that both need the same air duct replaced on the right and left side under the dash. I can find round cloth air ducts all day, but can't find the square cloth air ducts needed for these cars. I have searched this website for anyone that may have found a place to get them and as of yet nothing. I am wondering if someone knows if these square air ducts are available or if they aren't what my options are to fix this issue.

I find it hard to believe that everyone out there either has no heat or is using duct tape to fix these. In my case I can't even use duct tape. Someone please help me !!!!!

 

are you talking about an A/C car? i have no idea where to get them. the one on the driver side is a real job to replace. the passenger side is not so bad. i have a good used set. if you would be interested in them send me a PM.
