I had the same experience with my dash pad in my 70 Challenger. It had more canyons than the state of Arizona.I got a cover and for awhile I pretended there were no cracks in it. A good friend of mine who had to sell his 70 R/T Challenger project sold me his black, 3 speaker, non-air, OEM dash pad in perfect, blemish free condition, for $100.00. I cleaned prepped it put it in and I'll never go back again. By the way I do have the factory AM/FM, multiplex, roll-dial 5-speaker stereo system and it still works.
