We recently test fit the 1963 hood and noticed that the body lines on the fresh air cowling were not crisp and didn't match the hood very well. If you've been following this blog you'll recall that this cowl received extensive repairs a couple years ago. Check out that repair here:
We decided to replace the existing (green) cowling with an original undamaged cowling (the red one).
The bonding strips were cleaned and fiberglass repairs were made where needed. The brown paper was used to keep resin off of the fire wall.
In this picture the hood and stripe are classic 1967 big block.
