Used, but uncracked dashes can be had anywhere from $40 - $100 from recyclers. New dashes are about $400-$500. $459 from Adsitco. I got one off of E-Bay (waiting for the postman to arrive with a really long box) for my '85. Going to custom fit koa wood trim before installing.

Not looking forward to this job, but it may be fun. Here's a pic from Glen's 16V without the dash when he replaced the heater core.
