So i know there are some post on here on how to do this and that you can or cannot use a passenger side cushion on the drivers side. Well on the 01-04 you can. I went to my local junk yard (LKQ) last weekend to test the theory. I found a passenger side cushion out of a 01 sport and just ripped the seat to get it out. Other post have said that the number stamped on the seat was the same and that is true...it is. It is the exact same part number. I could tell right away it was in much better condition than mine and the truck it came out of wasn't the best condition truck. But it made sense that the passenger side saw a lot less asses then the drivers. $6.00 and i was out the door (They had a sale..$14.00 otherwise). Changing it out was SIMPLE!!! Just pull your seat out with 4 bolts and 2 seatbelt bolts and its out. The cushion is held in by 8 clip style holders that you can pull off with no tools. Then there is velcro on top of cushion under the seat cover that you just slide your hand under the seat cover to push apart. Optional is to get some thick foil tape and run it on top of the metal seat frame to keep the cushion from rubbing on the metal and causing the same problem down the road.That easy. Reverse to put back together. It took me a half hour. GUYS this is a must do!! I was so impressed with how much better the seat looks and feels. It's not flat anymore,it has the bolstering back on the sides,and i sit up higher in the seat. For anyone who has this problem with there seat its really this easy to fix. I cannot tell you how much more enjoyable my truck is to drive with the new to me cushion!!! Just wanted to share this with you so everyone knows you CAN use a passenger side cushion on the drivers side.
