Master cylinder / proportioning valve question

Should the 78 4x4 in my signature have a proportioning valve hanging off the master cylinder (like my 72 Blazer has)? I just got the truck a couple months ago and currently the brake lines screw directly into the master cylinder. I don't have a pic of my exact master cylinder but here one just like it...13" rear brakes and heavier GVW rating.

Should be mounted to the first frame crossmember behind the Radiator Support. Jay

Oh that's right! I've been submersed in the 67-72 world for so long I forgot, thanks.
