Awning rail

Just got back from a long weekend in our Bailey senator but on the way there my Tom Tom took me down the wrong road it was not wide enough so I had a miss hap and knocked the top of my awning rail luckily not on the side we use the awning. Does anyone have a clue how much it would cost to have it fixed? Plus do you  think  I would need a complete rail or can it be fixed by cutting a piece out and joining it. Thank you
