It’s sort of like cleaning out the garage. Get everything completely out so you have a clean slate to work with. Instead of all your junk in the driveway, fill up the truck bed with the interior parts. Then clean it up really good with a vacuum and broom, it will gross you out what’s been under the seat - stay calm. Load the new parts back up. My seat foam was in good shape so I installed a saddle blanket cover but with the seat removed, I was able to secure it really well. I ordered the complete plastic trim set. I also had the paint made but i ended up not using the paint because I liked the black color on the trim. New carpet went in easy, you have to trim a little for it to fit. I glued a crappy but overly expensive ($200 with shipping ) dash cover which looks good from a few feet away but the fit and finish is crummy. I wish I would have ponied up ($400-$500) for a complete dash pad replacement. It takes a while to get everything situated but in the end the results will make you want to spend time in the truck. I’m a huge fan of exterior patina and so that will never get redone but having a brand new interior is very cool.
