Does anyone make the plastic liners that install underneath the door panel?

I would get some plastic sheet from the hardware store and make your own.

I've never seen a vendor have them listed.

hello,actually doing the samething now (installing my interior) i bought a roll of rubber sticky sound deadener. came in a roll i'm going to cut to fit the same as the plastic did then stick it on. i know a few guys have done this and works great quieter inside and the doors sound solid when closing. putting it on the floor and rear under the 1/4 windows.hope this helps.i still have my original plastic to make the template if you need to be super correct. ON a second note have you had a trouble with your package tray fitting,almost like it's not long enough? Darren

My package tray fit fine.....maybe your tray could be cut wrong?????

hadn't thought about that, can NE1 measure there package tray length? would be appreciated.thanks Darren...sorry,not trying to high jack thread

I happen to have my interior out to put those plastic sheets under the door panels......I'll get ya a measurement today.

thank you gg70rrsixpack,seems we may be at about the same assembly point on are road runners.got my rear glass and 1/4 pop out windows in earlier now doing the sound deadner and interior install.i'll measure mine when i get home from work,very curious if yours is bigger

I actually have mine done....just finishing small details....Package tray measures 56 3/4" from end to end. Hope this helps
