Hi all, First post to the site. Total noob so please be gentle. Just picked up a 1970 K5, trying to fix interior door panels. Prior owner had them held up (barely) with screws that don't fit/hold. I have ordered the correct replacement screws from LMC Truck, but wasn't sure what they screw into. Are there inserts to go into the holes on the door in order to hold the panels in place? Thanks for the help and, again, sorry for what I am sure is an obvious question/answer.
