This is a right 1/4 window channel sash for a 1930's Ford. Check the orientation of the lower bracket to confirm its the correct side for your needs. Its 14 1/8" long. The bracket is 6 1/4" long and has 3 1/8" on one end and 6 3/4" on the other. By removing the bracket and flipping it, it could be made to fit the other side I think. Free shipping, usually same day.
