Why dont you just use two tie downs to ensure blades are level instead of the front blade being way up in the air?? It works for me
you can even make the front one a fixed length and put a hook on it to attatch to a cargo mirror bracket or make the front strap a Y strap and screw some P'clips to the toes of your JR skids....
The screws and the holes they go in already exist!!
The rear tiedown remains the same so you can put some slight tension on when tying down.
Just a thought
