Due to the fact '67-'72 seats are interchangeable, please refer to Image 5 to confirm the correct year of brackets needed. This is a must have for anyone who has noticed that the original seat position is TOO HIGH in the cab. These brackets correct the line of sight through your windshield, pedal angles, seating position and overall comfortability of the stock bench seat. We've designed these brackets to solve all of these issues with minimal install time and effort. These brackets will lower the seat approximately 2 inches. It was necessary to eliminate the factory sliding function in order to get the desired drop, so BROTHERS corrected this by adding slotted mounting holes to allow 1-1/4" fore and aft adjustability (Low Hump applications only). You're going to love the extra room this custom bracket set gives you! NOTE: Please reference Picture 5 to confirm which brackets you need.
