2011 E350 question
 

First post as I am new here but just purchased a 2011 E-350 12-passenger van. I suppose I am celebrating the Econoline's 50th as I owned a 1961 Econoline window van I put 264K miles on. Anyway I am looking for a source to finish off the floor plate seat bolt openings in the carpeting for a simple van conversion with folding bed. Any suggestions as the OE seats aren't of any real use to me?

Thanks
