I had to do minds also but on a201 . Itook both tires off and pulled it off and used it to draw the radias of the new one on some old plywood i had and sprayed it with some under coat i had left from during my truck They said you can by it a wal -mart? It's easer to get to the bolts leave in the fram i just took a small hand griner and grind the bolts off the one's that was to rust to turn. I used the same carpetbut minds lap over just lap and glued with some indoor /out door spray glue then stapled it with (ss) and new ss bolts which i got it all at home-depote has last about 2 yrs now the one's that came from the factory was made out obs board and sprayed with some kind of expory the other one is still holding up. IF yours don't lap just glue it then staple it ar if you replace i would lap new carpet looks a little better you can do it
