Welcome to the family, Bruce. Not just this worldwide 'support-group' for fanatics of all things GT40 related, but to that smaller fraternity of those terrified with getting into their first build. Intimidated really isn't the word, no, scary is more what you are thinking, right?
From where I sit, you should have no trouble at all in attracting help while you're in the middle of the build... Las Vegas and a fellow GT builder in need of help... sounds like a weekend trip to me! It may cost you a beer or twelve, but then you probably expected that anyway.
As you know there's a good number of CAV owners here, and I know if you reach out to them, they'll not leave you hanging. Be sure to check out the CAV registry so you'll know who's who.
And early happy birthday wishes! Since you brought up the topic of birthdays in your initial post, mine is coming up (I couldn't help but notice that you sure know how to buy great gifts).
Looking forward to seeing your build thread.
Best,
T.
