Ditzler paint code 50785, called "rocky mountain insurance" special paint.
The Rocky Mountain Life Insurance Company Cougars were a package of specially prepared 1969 Cougars.
There were 98 XR-7s ordered with special WT9083 paint by the Rocky Mountain Insurance Company of Calgary, Alberta Canada as a bonus for outstanding sales performance by their employees.
All of these cars were sold by Universal Sales and Service of Calgary, Alberta. The cars were leased to Rocky Mountain Life Insurance Company through Hillcrest General Leasing.
The cars were all ordered with the same options: special paint, white vinyl roof, white leather interior, bucket seats, deluxe seat & front shoulder belts, sports console, AM Stereophonic tape player, tilt away steering wheel, power steering, tinted glass all around, front power disc brakes, 351 4V Windsor, heavy duty battery, immersion block heaters, FMX transmission, door protection edge guards, front bumper guards, and wheel wire covers.
The rest of the story is that Rocky Mountain went out of business early in 1970 and the cars were recalled by the lease company and sold to the public.
15 are still known to exist
