Or build your own setup.

raise it toward the body 4 inches, make your own bracket. Quite simple if you do that

Any real downside to just getting rid of it and running new lines? That's what I had planned to do...

[Crunchy Taco]

I got rid of it and just ran lines its been fine for years loaded down or not. The only thing good about it was it made the rear brakes more sensitive when loaded down. I still carry a half ton of scrap once and awhile and my brakes work just fine.
