Just installed a set on my 68 and they look great. Exacto knife to trim the hole for the remote mirror knob and presto fantastic looking doors. So some will be left with the question do I keep the dreary , crappy originals because they are only original once pieces, or change them out to match their great looking cars? No one will know or ask questions or pull out a set of micrometers and test the thickness. If you are going for concourse trophys then you know what to do, good luck on what ever choice you make. NPD panels are beautifull!
