I looked for these as well and was unsuccessful. I reused the evaporator to case seal as it's heavy and was in good condition. For all other seals, there's a vendor that sells a sheet of 3mm thick dense foam material on e bay, that's 17" wide and sold by the foot. I cut my own gaskets and attached them to one side of all mating surfaces and then screwed the halves together. You wuold have to make all the cutouts for screw holes, etc., but it worked out well for me.
Good luck.
