The gasket between the actuator and intake manifold isn't resin or anything like that, it's green colored PAPER. That's what heat and torque do to it, makes it brittle and shiny looking. Be sure to order a couple of then for reassembly, the first time you will no doubt goof and ruin one. They say you're supposed to replace the 4 bolts as well.
It's a good idea to go ahead and order the breather tubes as well, as the are usually too brittle (no matter how nice they seem) to allow an easy reinsertion into the "Hell Hole" as most mechanics who've done this job on a 119 call the chasm that the throttle motor fits into. Spraying a little soapy water onto the tube will help keep it from getting yanked off when trying to reinsert.
