the dash really isn't that big of a deal. you just need to gut the truck and swap over everything one bit at a time. several guys here have done it and I'm sure they'd love to help you along. :thumbsup:
if it hasn't cracked yet, it's probably fine. :cheers: also, tech Qs should really go in the tech forum so more guys will see it and the answers will show up in the searchable database. :thumbsup:
