i thought i might have a short one, but all of mine are long ones as well.
looking at the picture, it "appears" the short side "may" be close to the length of the front side to the edge of the tie bar.
if it were me, i would do a couple of small cuts and trial fit until the exact length is reached for your application.
i wished i could be of more help, but at least this will bump you back to the top.
hopefully, someone may be able to give the exact length.
