You guys are a bad influence on me. The 67-68 hood look is getting to me. So, I need some info. I ran a search and found most of the info scattered among many differant posts and mixed in with Chevy info. I am trying to pull just the GMC info all together. My goal is 67 hood with my 70 grill. My truck is a 70

, so my fenders are good to go.
I have found a so-so 67 Chevy C30 junk yard truck with all the parts including a hood with dent in the middle. The hood may be too far gone as I think the at least one bolt hole is messed up. The fenders,inner/outer, left & right, are a mess too, so a whole clip is not really a good deal here.
My main concern is what parts do I need to get? Other than the hood of course.
1.Do I need the grill 67 top bar or not?
YES
2. Eliminate the eyebrows???
YES
3. Do I need the 67 rad suport at all?
NO
4. I believe I will need the 67 hood latch.
YES
5. 67 grill suport? What is that?
6. What am I missing?
7. And can I go back easily if I need to?
