I jumped in with both feet and said f&%$ it and drilled out all the spot welds for the stock metal dash. I then had drill out a crap ton more spot wells on the 65 dash that I have. It's now mocked into place and I'm looking for advice from the ones that have done this before. I wish I could tag mooseknuckles and KQQL IT like facebook.
