8-3/4 parking brake cable clip location

So, my 68 Dart came with a 7-1/4 rear. I have an 8-3/4 rear for the car now. I had a longer housing cut down to fit. I'm assembling the rear now and just discovered an issue.

Looking back at pictures of my original 7-1/4, there is a clip on the front side of the right hand axle tube that the right side e-brake cable passes through. I don't have this clip on my 8-3/4. I sold the 7-1/4 years ago so I can't measure off of it.

If someone could give me a measurement to that clip I would really appreciate it. I had the axle cut down narrower than stock A-body width so a measurement from that clip to the INSIDE of the perch would be perfect.
