My 68 coronet wagon has only 30k on it . It is only a driver so I don't see spending $1000 to get a firm feel box . I'm obviously in Canada By the time I send a core and pay shipping exchange on the dollar its that much! The car drives excellent except the damn more power than steering mopar thimg.

I can remember reading somewhere that a restriction in the line or pump outlet will lessen the assist . Has anyone tried that? If the car had 130k on it I'd swap the box but it is a true survivor.

I also purchased a set of used aftermarket sway bars from Frankenduster at a swap meet few years ago. I may add these as I went with Hotchkis on my super bee .

I have done this in a few cars. It is a "Trial and error" deal.
I've added a few spacer/washers, tested, repeated the process until the steering felt tighter. It was tricky for me though. I'd find that a .120 thickness worked great in some but provided either no difference in some and too much in others.

The stock (obsolete) factory wheel-alignment setup with less caster for diagonal tires, makes for easier steering effort.
So make sure you car has a proper 'modern' wheel-alignment first, which increases the steering effort slightly.

^^^ Yup. Adding caster will increase the effort to turn the wheel off of center, which is about as close to "feel" as you're gonna get with the old over-boosted Mopar PS system.

ok a wheel alignment is the next move along with the sway bars and kyb front shocks ...

Those kyb shocks will 'improve the feel' allright. The feel of harshness and uncomfortable driving.
If the budget allows I would get something better than that.

Yeah, Sandy....SKIP those shocks and get the Bilsteins!

KYB's are the Radial T/A's of the shock world.

I know but believe it or not I still have to go to the usa to get them..maybe I'll get bilseins for the bee and put the old ( year or two?) kyb's on the wagon
