A36 Cabin Ducts - Tubing

I am going to replace the ducts for my air conditioned 1986 A36 while the floorboards are out for some repairs. Can anyone lead me down the right path? Double layer SCEET? Diameter? Length?

Also what sealant for fresh air duct? Mine seems to be missing sealant.

Measure the old ones for length and diameter and then install a double wall SCEET duct.
