I've done a lot of searching, but still haven't seen a definate answer. Is there a bed extender for the flareside? Will the Sport Trac model fit? Is there drilling required? What other options exist? The local parts guy is no help, and only has one listed which seems to be for a styleside. Some say the Sport Trac will work, others say no. Some say the 1997-2003 and 04 heritage bed is the same as 04-08 new flareside bed, others say different. The cheap "one size fits all" on ebay don't look too promising. What have others found?
