How much does a 1973-76 Duster factory deck lid weigh?

I just weighed my 75 Duster lid not long ago. I will have to look when I get home. Don't have the paper with all the weights I have taken with me and I don't remember what it was. Don't think it was much over 30LB though. I am just using a bathroom scale so don't know how close it is. I hold the part then subtract my weight.
