Well I went ahead and cut the dash, I still need to trim the opening a little because it wee bit to tight. The wood grain is a challenge to cut, I had my dad helping me and I think he may have gone a little too far on one side, We will have to see once it's all together. I will post a pic later.
thanks for everyone input, It wasn't as painful as I thought.
I did take my time and didn't use any power tools, didn't want them to get out of control.
Thanks again.
