I replaced my dash about 2 years ago. I contacted Just Dashes based in California and they told me that I needed to remove my old cracked dash and send it to them. The process then starts with the removal of the vinyl and foam and leaves the just the plastic skeleton. If there aren't any broken area's, they reapply new foam that's better than the original. Then a correct grain vinyl is shrink applied onto the dash.
My dash did have some damage in the plastic skeleton and I was told it was unusable. They told me that I can purchase an already done dash for $1,400.00. Yes, it seemed like a lot of money - but the dash IS BEAUTIFUL! I get complements from everyone I meet at car shows. If you want the best - call Just Dashes.
