Looking for Discontinued Shingles

I need Owens Corning Promenence Driftwood shingles.

We are servicing a condo community that has these shingles and they are only around 10 years old. Unfortunately, chimney flashings and vent pipe flashings need changed (they were not replaced when the shingles were replaced!) and this style of shingle is now obsolete and we can't find an acceptable match for the management company.

Please contact me if you have any at all that you are willing to part with.

THANX!!
