I used superior dash pads out of payne (sp?) ohio. ran about 450 I think and I didn't need to send in a core. seemed like an ok pad, grain was a little off and some of the seems along the dash frame and pad were'nt very crisp. over-all its better than a cracked dash pad and way better than a dash cap. btw, the dash pad between an a/c car and non a/c car is the same.
