convertible hood frame issue

[Father]

My hood frame is out of alignment following a battery failure and manual closure. The drivers side of the  frame of the hood meets the windscreen about 15mm before the passenger side. This results in a loud clunk as the clamping hook drops into the lock in the windscreen frame. Once home, everything works fine. I think there's some adjustment in the throw of the hood using a section of the frame just by the rear side window, with the hood half closed you can see a short threaded bar which looks like it screws in and out, giving adjustment. Is this the case? 

Thanks
