How To Simplify Parking Brake Cable Routing?

Hey Dibs, sorry to take a left turn here, but after I had frame connectors welded to my '66, we drilled/reamed a hole for the front cable to go through the frame connector on the driver's side. I found the front cable needs to be just a little longer. When I pull the parking brake handle, the union of the cables hits the inner side of the frame connector and won't completely pull the cable tighter.
If I park on a level lot, it's fine, but on a slanted driveway, she wants to roll. (In the meantime, I just put it in gear.) Have you run into this yet?
