8 3/4 Naked lenght?

Anyone know the dimension of an A-body 8 3/4 Housing without the axels in it? I have one sitting here that I wanted to sell to another FABO member but when he came over we got to measuring it and perch widths don't match any know dimension for any body style, 43.5 inches. And guessing how far the flanges are from the ends doesn't come close to anything either.
