What PARTS did Hurst and Chrysler put in the Super Stock Barracuda & Dart not in other factory cars

Hello everybody. Here are a few things that I have learned and I "believe" to be true.
..The fan used is an aluminum bladed fan that was found in C body's that year.
..The "070" fan clutch is correct for these cars.
..On the Darts the front bumper brackets were thinner but they also deleted the two outward brackets.
..Bob Torozzi told me the was they made the bumpers were they took two sheet of steel that equaled the same thickness of a stock bumper, put them in the bumper press and stamped them. Then they prayed out the inner bumper and used the outer bumper. He said it was a real pain in the butt.
..Bob also said the rear ends were B body rear ends but the spring purchase were moved for the new spring location.
..The first run of Darts ( I think it was Darts but it might of been the Cudas) the front fenders and hood were Blue gel coat, not black gel coat. Major vender problems.
..Bob designed the k member but the vender that made the k member did a very poor job making them. Many of these cars had the headers delivered in the trunk because of poor header fitment.
..Last but not least. On the Darts, there were THREE different wheel well cutouts shapes. The first design.....in the front of the wheel well goes straight up and down. This did not work well when the cars went super stock racing. The second and third design, the area in the front of the wheel went down at an angle and that made more room for taller tires.
..one more thing...these cars were thrown together by non union workers. They did not give a darn about these cars and they made things work. I heard from two different people that Hurst had 20 minutes to cut, bang and weld the rear wheels....both sides!! They did what they had to do to get the cars out the door. If they ran out of thin glass.....they put in thick glass. If they ran out of thin bumper bracket then they put in stock bumper brackets.
Hope this helps.
