I am manager of a Cadillac dealership bodyshop, I work during the day so I will not be of help until the evening hours. Sounds like you already have it figured out though. If you need assistance shoot me a note & I will get back to you in the evening!
What hood type are you replacing it with? That will be a big help in answering your question. If it from a donor Trans Am ( original equipment) or is it a A/M builder, the question will be much easier to answer!
1981 grave yard vehicle, restored by another totaled T/A to what you see here. Body was finished to current pics back in fall of 2000. It has a 455 Pontiac that is fresh, it's a nice driver! I like my 2nd gen Trans Am and can answer bodyshop questions you may have.
