427 Front Fender Flares - 3 Original Styles?

[REDSC400]

In looking at pictures of original 427 Cobras from 1965-67, it appears there are perhaps three basic front fender flares with the major difference to the eye being the bottom rear of the flare or what you might call, for lack of a better word, "the mud flap or gravel deflector" area.

Type 1 or Widest:

It appears that the real S/C cars had the widest mud flap area.
These cars also tend not to have the glove box. These could be about 4 inches wider than Type 3 at the bottom of the flare, near the undercarriage.

Type 2 or Somewhat Wide:

Then there are the second type, also S/C with a wide mud flap area but less than the Type 1. These flares are perhaps 2 inches wider than the Type 3 flare at the bottom. These cars tend to not have the glove box.

Type 3 or Least Wide:

This trimmed back mud-flappless flare appears on cars that were originally street roadsters (Not S/C's), and tend to have under car exhaust systems. These cars tend to have the glove box even if they now have (retrofitted) side exhaust.

Does anyone else have any data or anything else to add on these flares and their attributes to 427 type?
