E-brake cable tab on 8 3/4 housing

My 68 Dart originally came with a 7 1/4 rear. I had a old 8 3/4 housing shortened to fit. The replacement housing doesn't have the tab on the passengers side axle tube for the e-brake cable. Does anyone have a measurement of where that tab should be placed on an 8 3/4? The original 7 1/4 is gone.

I had the housing shortened to 51 1/4" so I'd like a measurement from the center section to the tab. Thanks
