Align ‘67 Barracuda convertible top

Do the alignment pins drop into the pockets in the front header?
Has the top frame been removed from the car & Reinstalled?
Where the top bolts to the inner panels there are two 1/2" holes through the top frame and the body... Those set the frame position then adjustment can be made to the frame at various points... Drooping at the windows there is an adjustment for but typically once the top is stretched the frame is pulled tight & the windows no longer droop... I usually leave the adjustments as they are & just get the pins to drop in... Then stretch the top & if needed fine tune the adjustments from there...

The top should have fit the car originally, so if it goes back where it was it should be pretty close....
