Has anyone used the Speedway 1955-59 Chevy Pickup Duel Master Cylinder Adapter?

How much work is to install and add the needed brake lines to split the front and rear brake lines? Did you wind up needing to add a brake balancer? Would like to make this mod but I am in the middle of a major house remodel and can not get stuck spending days or weeks with my truck off the road if it is a complicated swap.

Thanks for any help
