In my opinion ... you have to remove the hood.



The bracket on the left is the front hood hinge. It goes on top of the shell and bolts thru to the brackets on the radiator. Then there are two bolts on each side ... of the shell. The three slots are for the cowl lacing.



With the hood hinge bracket removed, along with the 4 bolts on the sides ( 2 per side ) .. the shell should be able to be moved slightly forward and then lifted straight up. Fairly easy to do ... especially after you have done it a few times ...
