I have a bottle of the good old fashion Chrysler Steering fluid from the 90s but I reserve it for my own vehicle.
Moving on to address the slop in the steering on this 72 RR, I am replacing the steering box with a freshly rebuilt one from Firm Feel. The local shop brings fluids and additives from the States and he has Castrol GT Power Steering fluid. Looking on their website I can't read anything about the product. Will this stuff work or is nothing more than ATF fluid in a fancy bottle?

It could be used for power steering but not what is recommended by Mopar or anyone else.
A great many threads on this forum are devoted to circumventing what the factory recommends.
Every time this subject is broached the comments are predictable...."don't do it", "it's not formulated the same" but nobody has ever provided proof of damage that can be 100% attributed to using ATF.
John,the only fact that I can attest to is that about 30 yrs ago I put ATF in a new pump on a 65 Monaco.One year later the ATF was almost black and you could get a black film on you finger just by wiping it on the inside of the reservoir.I cleaned everything,put in power steering fluid and and the color never changed after that.

I'm no engineer but when all the automotive manufacturers call for power steering fluid and not ATf there must be a good reason. I do know that ATF is thinner than power steering fluid which tells me it lubes better when hot and for a longer time.
I don't get why people even want to run non-recommended fluids here. Am I missing something where ATF is a fraction of the price of power steering fluid or something?? Maybe it's the 'cool' thing to do?

Seal compatibility is another often cited myth, look at the P/N of seals/O rings in late seventies boxes and you'll see numbers like 15xxxxx or 17xxxxx that date back to the Type "A" days.

I didn't mean to cause such a stir with this...I just don't have the luxury of ordering from Summit because they won't ship the fluid internationally.
I am going to call Firm Feel tomorrow and ask them if they think the Castrol is sufficient for the job at hand.

Just because the part number is the same doesn't mean the rubber is the same. BTW did you look at the FSM page above where it says NOT to use type A trans fluid?

I just got off the phone with Dick at FF and he said the Castrol is fine. Just in case anyone looks through a search later on and finds this thread. Now I am off to paint the gearbox all nice and purty
