Help with headers, parking brake cable, & crossmember

[H20cooled]

Hello! I installed a 4.8l with a 4l60e into my 68 c10, I used the 73+ frame mounts with the 73+ dirty dingo sliders, for the tranny cross member i used one of the cpp units, for headers I'm using the Doug Thorley THY-324Y-C headers. The engine and transmission are installed and look great, but looking at the headers/exhaust position the cpp transmission crossmember is too high for the headers and the parking brake cable is also in the way of the exhaust path. I thought the the cpp crossmember was supposed to work with these headers for clearance.

Attached are pictures. Any help/advice would be great.

Thanks
