I have major rust issues in my 89 RS, I was wondering if anyone has tried to use a complete 4th gen floor pan. I know where one is in the junk yard that I can get cheap but the problem, I'm looking to fix is the drain holes. They are horrible to hold water and rust out in the 3rd gen but in the 4th gen the grommet just pops out so much easier to fool with.. If anyone has tried lets hear your experiences with it, or if you think its possible to point.. I may section off the pans to fix what I need to rather than cut the whole thing out just may replace a few sections
