1968 Airbox rebuild question

Lemme know if you need anything, pics or parts wise. I grabbed a complete(but broken) one from a notch back for parts for my 69.
This is really helpful and I thank you for taking so much time to help. Yes, first time. Bought the car in 1984 while living in California. My plan was a slant six to 360 engine change. One thing led to another...
