Anybody having stiff but uncracked vinyl such as dash pads, arm rests, door panels and such should know about a product called Spray 303. It softens vinyl back to almost new condition. It works so well that I was able to remove the original dash pad from my 58 (lots of weird bends and curves) to repad it. It seems to work on just about any plastic I've tried it on including the lower windshield molding and B pillar covers. I found this web site http://www.properautocare.com/303auti.html and I feel that after using this product that all their claims are true. BTW: I don't have shares in it, unfortunately.
