I have an excellent reproduction of these filler strips in the works. I've already approved first articles and should have parts in hand within a few weeks. They'll be priced at $15 plus shipping for a set of two.
I haven't found anything that documents a service part number for these filler strips. My cross-reference manuals don't list the D0ZB-61101B62 engineering number, and I don't see the part in any of my body illustration manuals. Does anyone know if these were ever available as service parts?
