OK
I mistakenly thought “swapping out” meant changing the style/type of brakes.
I would replace all wheel cylinders, as you suggest.
If you plan to keep the truck for a while, replace the Master Cylinder.
Also, bleed your existing brakes thoroughly before replacing any parts. This will get “junk” out of the brake lines, before installing wheel cylinders and master cylinders.
If your brake lines look questionable, you might want to consider replacing the, with stainless steel lines, if you plan to keep the truck for a long time.
The $$ adds up, but the brakes and front end components are very important to safe driving.
Follow the Shop Manual instructions and you should be OK.
Check the condition of the front wheel bearings and races.
Do not be surprised if they are scored/etc and need replacing.
Have you check the front steering pars, as per the description in the Shop Manual?
I think the 1954 truck Shop Manual brakes are the same as yours? . Someone will correct me, if this is wrong.
