Ok i already took off the side skirts on my 87 z-28 but i cant seem to get the other part of the side skirt off, you know, the part that is connected to the door i took off the door panel and took out 2 of the bolts and the 3rd one like broke on me but i also noticed 2 bolt things on each far side ,and they were all rusty i pulled one a few times and it like fell apart but there is a bolt sticking through and i just cant seem to get it the dumb piece off

 

go practice at a junkyard, that way if you break something no big deal.
