Default Complete Fluid Flush on 98 Cobra

Ok guys since i bought the car used and not sure what has been done when. I can going to completely drain every bit of liquid from the car, clean the engine sludge with some BG(i think was the name), cooling system etc and replace with new fluids.
Anyone have any "must use" liquids they could tell me about?
From what I have read I was thinking Mobile 1 Syn 10w 30 for motor oil
What about the rest?
Motor
Brakes
Cooling
Power Steering
Rear end
Transmission(5 Speed)
Anything else you would recommend flushing?

Any more specifics on weights or anything?
I see advanced carries it and they have plenty in stock so i will head there to pick it up. The car isnt blown and no nitrous. Just long tubes, mufflers etc.
No major mods. Does Royal purple make all the fluids i listed? I couldnt find any power steering or brake fluid
I did find gear oil and motor oil
I am assuming 10w 30 motor oil and would i use the 75w-90 gear oil in the tranny

Another vote for Royal Purple! I run it in the cobra and svtf, wouldn't run anything else.

for the pwer steering fluid just use whatever ford recomends for the car. thats what i use in mine and i have no issues with it. as for the brake fluid try and upgrade to dot 4. dont use dot 5 unless you are going to use it for strict racing.

I'm running Mobil 1 Synthetic ATF (Dextron 3) for PS fluid...that's what Ford calls for on the 03/04 Cobra!

Got all the Royal Purple
Gear Oil
Tranny fluid
Motor Oil
Coolant

Now my question is what is a good Engine and Tranny Flush other than having someone hook it up to a machine? What about Cooling system flush?
Or am i better off letting a shop do it?

well the only way to get all the old fluid out and replaced is to take the tranny apart, clean it, and reassemble it with the new tranny fluid. then all you need to do is drain the cooling system. all of it. run water through it and drain it again. then you should be able to fill it with the new coolant. so unless you feel you could do these tasks id let a shop do it.

Yea I was was really looking more into a good product to use to remove engine sludge and a good product for like the fuel and induction system etc.
I know if i take the car to the Ford dealer here they have the BG equipment they hook up and run the product through the engine, they have a diff service for transmission as well as for the cooling system.
I just didnt know if there was a product out there i could run through the engine, tranny, cooling system etc to get unwanted sludge etc out of it without having to have them hook it up to their machines and charge a ton !
