Took some time today to unpack all the used and (one) new black headliner pieces and parts I've acquired to make sure they are all in usable shape. Everything looks decent and ready to be recovered in the new black headliner cloth this, or next month.
My new intake boot/cover showed up from Pelican so I popped it in this am as well. The old one was completely shot and no amount of epoxy would keep the uppper and lower halves together. It fit so tightly to the fresh air boot that I didn't force the two pieces together as I think trying to uncouple these parts is what must have caused the OEM piece to fail over the years.
