all i can say is a lot of the stuff is still junk .i did my trunk pan. my dad did not have a truck but a gto . when i did get the car back i did use it the same way. to hall big blocks in it to. so it was mich rust and bent up. the repop pan they told me was 18 gage was not. if it was not so bent up i would of use only that i need and not used the hole pan you my want to find a gm fender and put the heal on it you can buy part of the fender the ohly thing that i used that was repop that i have been happy with is the interior parts and the new rocker moldings
