Right: Rock Auto WC 18291, or NAPA UP 18291.
Left: Rock Auto WC 18290, or NAPA UP 18290.

Its an old reference and I can't personally verify it so I suggest you confirm before purchase.

Is there a specific brake fluid i should be using, or that is highly recommended by all.

I have NON power brakes on my 53.

Unless the entire hydraulic system has been flushed thoroughly with alcohol and dried, you must stick with a fluid compatible with what's in or was last in the system, and to do that you have to identify the prior/current fluid, usually done by color and odor. DOT 3 and DOT 4 are mutually compatible. Silicone fluid (DOT 5), which has some advocates, is compatiible with nothing else. Silicone DOT 5 has the advantage that it doesn't absorb moisture over time, also has some disadvantages (voids warranties by some system component rebuilders, thinner and a little more prone to leaking). Often Silicone is the better choice for museum (stationary) cars or those that will be laid up in long storage.

If you use conventional fluid DOT 3 or 4, live in a humid climate and drive the car only occasionally, changing the fluid every 3-5 years is a good practice.

I'm a fan of DOT 4.

Unfortunately, I do not know what is currently running through the system. I will top it off with some dot 4. Thank you

I strongly suggest you attempt to determine what fluid type is currently in the system before you "top it off" with anything. What color is the current fluid? Silicone fluid is usually purple. Rub a little between your fingers and compare that to your DOT 4. As long as you'll be replacing wheel cylinders, I suggest you purge and flush the entire system before adding any fluid.
