Came across these on summit racing. Anyone have any experience or thoughts on these? How much fabbing is needed. I'd love something like this.

Are those components really substantial enough to be under a Chrysler C-body, considering their Mustang II heritage?
 
I might "see" it under a pre-UniBody car, but the weight capabilities of the Mustang II architecture might still be in question. The Mustang II steering and such have been popular for the street rod applicaitons, for decades, but those were generally lighter vehicles.

Just some thoughts,

It's gonna be a ton of fabrication and nobody here is gonna be able to help you.

The Mustang II stuff if great for street rods etc. The geometry is for a short, narrow car. They stretch the center to make it kinda work with a wider car. It's just not gonna work real well with a longer, wider car.

Then there's the kit... 54-64? That represents 3 or 4 different frame designs within the Chrysler line up. It can't bolt up to all of them.

The next thing is fabrication. Are you willing to do all the cutting/welding/measuring/fabrication etc.? It's not for the faint of heart. Finding a good shop to do it will be $$$. And that's if you can find a shop that can do it right.

The better alternative is to tighten up what's there... Maybe add sway bars. The torsion bar suspension was state of the art when the car was new. It's still a good design. Putting this garbage on the car isn't going to make the car handle any better... In fact, I'd bet on it making it worse.
 
The weight is certainly an issue, but you would do that to a valuable car like a 300k, why?

Boom, that's the answer I was looking for. Thanks Dave.
 
New i just need to find an after market sway bar. Haven't found one yet for this model. Thanks for your input.

You'll not likely find anything plug and play for that car.

A couple of options are to find something in a salvage yard that can be made to fit the available space. I've read where a bar from a 70's square body GM pickup can be cut down at the ends and made to work on a Cbody using universal bushings and end links. Your car isn't a Cbody but the suspensions and dimensions should be similar.

Heating and bending the ends in or out to adjust the width will NOT work, they just break.

The GM bar is too long and too wide at the ends so you can cut it back and have the ends machined to install end links. Be prepared for some trial and error. Lol

Option #2 is a 3 peice NASCAR type kit that uses a straight splined bar with removable arms. The upside to this is being able to choose exactly the right diameter bar for your application. Downside is making it fit the confines of the chassis.

Sway Bars and Parts

You might check the parts books and service manuals at www.jholst.net to see if there are any different-sized factory front bars for different models. Police/taxi, 300 Letter Car, station wagon, etc.

Just some thoughts,

Unfortunately, my research yielded zilch in that area. Other than the CPD bars and the Imperial bars look the same, in their shape and mounting. The part numbers seem to be anchored in the later 1950s, too. Everything changed for the 1965 C-body cars.

The interesting thing is that the '65 B-body illustrations look very similar (bar configuration) to the 1964 Chrysler items, other than the bushings and retainers the bars mount in. For the front supports and the "retainers" to the front strut bars. Fashioning the end atrtachment bushings our of urethane might be an option, though?

The GM pickup truck front sway bars, which possibly go back to 1967 rather than 1973, have a stub end where they go into a rubber insulator which is u-clamped to the lower control arm. Most are about 1.0+" in diameter and the rubber has some urethane replacements (aftermarket), I believe. The '67-'72 2wd models will have a narrower track than the '73+ models will. Might use the '65+ C-body sway bar-to-strut rod mounts with those bars, depending upon the width of the two bars and strut rods? For that matter, as the front supports are only a pivot point, it would be the end-width, combined with the later C-body mounts to the strut rods that would allow later model C-body bars to be used? For which there might be some larger aftermarket bars available?

I believe that Helwig used to make rear bars, to balance out the larger front bars? From there, it would be some 15x7 OEM wheels, HD shocks, and better tires.

Possbilities?

Yeah, I think I'm going to try to piece together the GM sway bars. Still want to find a beefier torison bar, unfortunately might not be reasonable. I REALLY appreciate your help, love this site!
 
Seems like we got the IFS kit cancelled, which was a good decision.
One thing we didn't mention, though, that might have been an ordeal - you would've needed to find somebody to do a wheel alignment, and I wonder if most shops would turn you away, not being sure if they could do it correctly. They can make their money doing 3 Toyotas or 1 confabulated old car....
