I have a Planeplastics brand upper panel overlay for a PA28-R200 (should fit any PA28 of that era), part K65839-03, in very good condition - it was in my plane 2 years before I replaced it with an aluminum custom overlay. Cost is $245 new. I'm not looking to sell, just bless a fellow pilot who may need it. You'll need to be willing to pick it up. I'm outside Philly at KPTW.
