Back in '04, 5, or sometime in there, (too long ago. Old Fart's Disease. CRS Can't Remember S^#t) when I did the CV rear bar swap in my wagon. There seemed to be many complaints of either breaking a sedan bar, by either cutting, welding, stretching,,,,,,. Or pulling bolts through, or breaking the LCA's
The ONLY alternative was $$$$ Hoskis, or however you spell them.
If one is going to do some all out (only) preformance driving,,,,,,. THEN, the MATCHED front/rear $$$$ Hoskis bars/upgraded controll arms/Bilstines/KYB's, are the only way to go.
However,,,,,,, (sigh) NOT everyone has the 'deep pockets' required to do such a suspension upgrade. It was either, break feces, do without, or spend lots of $$$$! NO inbetween!
Back then, I was in a U-pullit yard, helping a buddy pull some stuff off a Crown Vic Cop Car, for a Street Rod project. The CV was on it's side. I kept staring at the rear suspension/frame, because it look similiar to the Caprice. I went over to the Chevy section and found a wagon on it's side, and sure enough the frames looked identical. I went and got a tape measure. It was though the same company made the rear section of the frames/suspension for both the Ford and Chevy!
I found out something else that day. NOT ALL CV's had a rear bar! ONLY the Cop CV's had rear bars.
The design of the CV bar was that, like on EVERY rear bar set up I had seen, EXCEPT for the GM! Bar mounted to the rear end housing, and link bolts mounted to the frame.
Yes! Granted, the CV bar was small diametered compaired to the LCA mounted GM bars.
But, IT WORKED! 20-30 mph FASTER, confortably through the same turns, w/o the rear C'Vic bar!
I took pictures of the mounting process I did, posted 'em over on the SS site, that I found a cheap alternative to the $$$$ Hoskis/LCA problem, set up, that gave the same handling results!
You would have thought I commited a raging sin against God or something, the way I was 'ratted' on, by the tried and true Hoskis (only) method. "NO self respecting person would EVER put a Ford part on a GM,,,,,,," Yadda, yadda, yadda! On and on and on! I was an inbread moron, etc, Geeze! Even one of the Mods gave me hell! I quit. To hell with 'em if they didn't want a better 'mousetrap!'
Then, they had the 'big crash' and the thread/pictures I did/posted, got 'lost'
Then several years later, 'someone' either remembered that post, or like me, discovered that the CV bar would bolt on the wagons, vastly improve the handling, resurrected the thread. Now several are doing the CV rear bar swap! With NO LCA problems!
What blew my mind was, someone said, they went to the Ford DEALER, and bought a NEW, larger diameter, C'Vic Police package rear bar for a measley $60!
There is a book that ADDICO put out a decade or two ago. I don't know if they still have the book or not,,,,,. But it's worth EVERYONES time and effort, to get that book and read it! There is a WEALTH of knowlege of suspension design, and common myths/mistakes/etc. I think, it's called " Handling. What It Is, and How To Get It"
