73 duster manual sunroof help

I just ran across your thread wanting information on 73 340 sunroof cars.
I own a 73 dart sport 340 with the sunroof and the fold down rear seat.
My parents originally bought the car in 1975 and it has been in our family ever since. It is a b3 bright blue with white vinyl top and side stripe with black interior. I still own it and am in the process of building it up.
