Just watch it carefully as you close it, and see what way it needs to be moved to close properly. I just went through this when I installed my cowl hood. I had to drill out new holes and make some modifications to mine, but you just need to figure out where yours was and put it back there, and it will work fine. There is adjustments on the piece that mounts to the rad support, and also on the latch mechanism itself. just loosen the bolts, you can move it up, down, and side to side.
