The lengths have been know to be off. A dry fit might be helpful
I glued mine, only used the clips in the door channels at the bottoms
Also glued my anti rattle strip.. its held for 9 years so far.
I did not have a way to bend those staples.
Agreed, bending those tangs is going to be a challenge, the guys at Steele Rubber told me it was tempered steel and that they can break. Suggested using a piece of wood cut just wide enough to fit inside the run channel and an arbor press to "push" the run channel clip though the metal backing and then crimp the tangs with a punch after turning the run channel over and removing the wood strip. Suggested that would allow the tangs to go into the soft wood. I'll update you how this turns out. Thanks, again, Dads50.
