Welcome, nice fleet of cars you have there. I grew up on long island (Holbrook). Moved around until I settled here, in the middle of the Pacific ocean.
There is a memeber on FBBO, goes by Maui Jim. He joined on 8/5 after buying 67 charger that was in storage in Lahaina for over 10 years. He did not have chance to get it out before the fires. He is okay, lives on another part of Maui. But the car is lost.
Since your not planning to go back to factory original, numbers don't matter. If the front clip has been changed (Frame rails, inner fenders, core support). I would be more worried if it was done right. The FSM will have measurements you can check.
