Subframe connectors......

I've been researching subframe connector ideas/designs and have determined the 2"x3" laying "flat" and wrapping the rear frame stub is my best option. I got them cut & notched but noticed the bulge on the driver side trans crossmember where the parking brake cable exits is in the way of the connector landing plate. Thought about splitting the bulge and curling in the sides to make it flat or trying to form the landing plate to match the contour? Haven't seen any pics of anything like this - its a '73 Swinger. Should also mention I'm planning on a ladder bar setup with the crossmember being tied into the connectors. Any input, advice, or experience would be appreciated.
