Our 2007 Getaway has a good bit of wear to the tang and I would like to replace. Does anyone have tips on doing the replacement? At first I thought it would be straight forward... Drill off the rivet heads, knock out the old rivets with a punch, use some sort of sealer and rivet on the new one... but I read there is a backing plate. I can imagine it will be knocked off or pushed back when driving out the rivets. I'm not sure if the backing plate is held in place by the foam core or not. Unfortunately, I re-glued a lose comp tip a year or so ago... Never thought of replacing the tang at that time.
one thought I had was try to knock one rivet out at a time and try using Cleco fasteners, like in body panel work, to hold the backing plate in place. I have not used these before but do a little fabrication, so I would have a use for them after purchasing. If you're not familiar with them look for a video. they are like a temporary rivet.
