Hood Insulation is gone. You can go to the parts counter and tell them you need a hood liner. If they ask for a year just say 2001 (they should all be the same from '94 to present). I believe the reported cost was around $50 for the liner, but they get ya on the fasteners. I think they are about $2/ea and it takes around 12-14. Might give Mopar4less a call (1-800-748-2139) and ask for internet parts sales. I just ordered the rear wheel liners for a 2002 I have on order. I paid $90 for liners, fasteners and shipping. Think the regular price was almost twice that!!
Some have report the "Oh I TRIED TO BY-PASS THE CUSSING FILTER" handle on the passenger side A-Pillar has been deleted, the 2002 trucks I test drove had them. Might be a matter of what trim level or plant the truck is made at as to if it comes with one or not. Also the lighted vanity mirrors have been deleted for awhile now.
If the search function worked you could find a thread specific to the deletion issue and what all else has been deleted over the years.
I made comment about all the deletions when ordering my truck and asked what's up with that. Sales lady just shrugged and said: I know, but if they can get away with it they will. We talked about the rear wheel liner issue and she said she thought the reason for the deletion is because Chevy and Ford are no longer doing it, so DC decided they did not need to any more. Kind of like "keeping up with the Jone's" type of thing. If the "other" puts something on thier truck and it helps sales, then everyone else follows ("keeping up with the Jone's"), guess the same applies when the competition decides to drop something.
