I found some at my local Auto Zone, although I’m sure any DIY auto place has it.
I used the larger (there are more than one kind) type that says its good for trucks and SUV’s.
It has its own gluing, so I made sure all of the old trim was removed, so I could get a good adhesion.
Also I drilled a very small hole and used a 1/8″ rivet to keep it in tact, as I don’t trust the manufacturers glue to hold with all of the compound curves around the doors.
It took some work and lots of convincing, I think but it turned out very well.
