65-66 Mustang Hood Differences no ribs to ribs?

[cboss70]

I used to have a picture that showed at some point Ford added ribs to the underside structure across the front of the 65-66 hood near hood pin. Does anyone know the transition dates from when the hoods had underneath ribs and didn't?

About mid-year production '66.  It happened around the same time as the raised triangle LH fender version, Jan '66.

Thanks. Just curious- did that transition to the ribbed structure also show up on Shelby hoods built around that time if not, what were the transition dates to the ribbed under structure on the Shelby hoods (if ever)?

Would not expect them both to align but have not done a complete survey yet. Challenge is that you need the dates from the frames to confirm that the cars your looking at are even possibly original to the cars and allot have been replace and swapped over the years. Would have to review the details but their may be multiple ribbed versions also. Making it even more of a challenge and this is not even bring in the all steel hoods to the mix

65 GT-350s were shipped from Milpitas w/o hoods. Steel/glass hood frames used on later 65s came from a source as yet undermined.

All 65/66 GT350's were shipped from Milpitas w/o hoods and not just 65's as your statement seems to imply.
