"Branded" Mustang special

Ford offered a dealer installed package called “Branded Mustang” in 1968 with patterned tops similar to the Mopar Mod Tops. There were two kits available, one for ’65-66 and one for ’67-68.

Branded edition Mustangs were created by dealerships on mostly used 65-68 Mustangs to spiff them up for resale. The Branding kit was available from Ford. The kit included choice of colored vinyl tops (in 15 colors), side stripes (in 5 colors), quarter panel chrome, and special Branded emblems.

the vinyl tops could be in four patterns - Paisley, Sculptured, Tweed, or Leather. They also came in 15 different colors. Or you could get just white or black. The stripes came in five different colors.

The Branded Mustang Kit was used by dealers on new and used Mustang coupes and was distributed by DSI Corp., Plymouth, Mich. directly to Ford Dealers.

It consisted of:
 1. Pre-cut, hand-sewn vinyl top - 15 different colors or patterns
2. Two black and brass or silver and black C-pillar emblems - marked left and right
 3. Left and right Screw-On quarter moldings - with Ford part numbers
4. Pre-cut "Thoroughbred" stripes in five colors (Red, white, black, blue, gold)
5. Two cans of Mastic glue
6. Ford instruction guide

 This all came in a 3 foot long shipping tube from DSI.

The tops are all different and range from 'pretty cool' to 'butt ugly'.
There also is a thoroughbred stripe identification chart.
