How wide was the front pad?
A formula to use as a rough estimate: Add 1 to 1 1/2 to the width in inches of the front foot and that will be the length of the bear skin in feet.
Examples: Add 1 to smaller bear and 1 1/2 to larger bear. For a 4" track it will be roughly a 5 foot bear. A 6" track will be roughly a 7 1/2 foot bear.
