CPP 500 steering box

Hey guys I just got my CPP 500 box in the mail today and I'm ready to install.is this a direct bolt on to my existing rag joint.I have a 62 with power steering.I'm so confused from what I have been reading.By using the CPP 500 box does it eliminate the slave cylinder and the control valve all together?if so would be great..do I need anything else?Directions seem a bit confusing and misleading. They actually sent me two sets of directions.for uses with the rjc 605L and the rjc 605s. Please help. Thanks guys

If all you have is the 'box', there's a bunch of additional parts required. Typically some are addressed in the instructions, some are not.

Also, the alignment specs change considerably. For example, the new 'box' requires somewhere in the vicinity of + 4 degrees of caster; the original stamped steel upper control arms were designed for +/- 1/2 degree. To achieve the caster required by the new 'box', you will need to replace the upper control arms with one that have a 'built in' 4 to 5 degrees of caster. I do not believe there are any stamped steel uppers with that much built in caster for your '62. So the expensive (but quite good) tubular uppers will be needed.

And, the new steering MAY be so sensitive that a front sway bar upgrade is required (my '63 did); which is more $.

Changing the power steering system is NOT the simple 'part bolt on' job that vendors tend to imply. They don't actually lie, but they tend to leave important things unsaid.

Here's link to some helpful (hopefully) info (it too is rather 'incomplete'):

Many people convert, but I like original myself.

You can get them rebuilt, or just go with a good used.

I have some good used ones available.

Everything you need to rebuild your steering system can be found on Corvette restoration sites. This is because this steering system (external hydraulic ram assist) was retained on the Corvette up through 1984 after the rest of Chevrolet's fleet went to the Saginaw self contained (internal ram) power assist in 1965.

Unfortunately because these parts bolt onto a Corvette the price increases over the same part sold to fit an Impala because 'vette owners are regularly forced to pay more; because they can (price of being rich). Same thing happens to Cadillac owners who pay twice as much for the same part that fits a Chevy.
