Boat trailer help

[BGcoreg]

Well I got rear ended pulling my boat a couple of weeks ago. Thankfully hardly any damage to boat/trailer. Had to get my winch post welded back on which was about the extent of it all. Finally getting around to setting it up how it was and now there is about a 2in gap between the front bunk board and my hull. I don't believe the trailer is bent or twisted somehow but something had to change. Should I just add to the front bunk board so it'll help support the hull ? Or maybe lower my back bunks and get them even with the front ? Not familiar with adjusting the how the boat rides on the trailer ImageUploadedByTapatalk1428604562.941667.jpgImageUploadedByTapatalk1428604571.256922.jpgImageUploadedByTapatalk1428604579.008868.jpg
