i got an 84 z and it has some nasty rust going on,the trunk pan around the inner quater are pretty much eatin,and the outer quaters arent to health either,the floor pan has about 8 quater sized holes right threw,how hard is it to remove the inner and outer quaters if there are still spot welds left and where can i find replacement outers,cuz i have a donor car with straight clean panels,but my friend whos an autobody man said i might as well buy new outer quaters cuz to remove the outers from the donor would warp them but the inners dont matter cuz weld them in seal it up and throw carpet over it no-one will see it,but the outers have to look good,and the floor pan im going to cut sections out of the donor car and weld them in instead of getting new floor pans right now,but the question im asking is it hard to remove them when they are rotted out,and whats the best place to get new ones,im in canada also,thanks
