SSandman - I saw this in the scrap bin in the shop last weekend and thought of your desire to have a more perimeter loading of the frame instead of the bracket shown above. I believe this is off a Dodge or Ford 5500/550 front damper (only) so it only sees the damper forces, not the whole weight of the car. But in concept, I think this is what you were getting at.
Sorry, nothing particularly useful here...but might be an inspiration or idea for someone?
Making something like that work would be ideal way to me!
Just as an update, I ended up going with a Speedtech kit front and rear. I went with the Speedtech bolt in front kit using their upper and lower control arms (upper portion of the spring mounts in the spring pocket distributing the load the same way the factory would). I also went with their bolt in rear kit. There's a much lower spring rate in the rear, so I feel OK about the shock mounts supporting the spring tension of the coil over but if I could start from scratch again with my chassis out I would have definitely reinforced the area of the rear shock tower, probably by tying the two towers together somehow.
The install on both kits went very smoothly, they appear to be very high quality parts.
I also installed their front sway bar, again a very nice piece, and their chassis mounted rear sway bar.
For the rear sway bar, I ended up using some Detroit Speed mounts I had lying around just because A) they were a little beefier and B) they allowed more versatility with how the rod ends would be mounted (it's a single tab instead of a dual tab where the rod end sits between, so I can install the rod end on either side). I also ordered some teflon lined rod ends to replace the speed tech steel to steel ones.
One issue I have had so far with the sway bar is it was very hard to find a good mounting point for them that allowed the end links to be perfectly vertical. I don't know if this really matters, as long as the rod ends have enough angle of travel and don't bind up during the articulation of the sway bar.
the chassis mounted sway bar seems like a great idea, but it's another one of these things where I really feel like I am 'half assing' by not fabricating up some sort of mounting point and reinforcing the area of the chassis where they mount to. Looking at many other kits that are sold though, they all appear to use the same style of mounts and the chassis on all of those cars have the same design/thickness as ours, so I'm assuming it's not really an issue.
Another issue with the chassis mounted sway bar is that it doesn't clear my CIA 3" exhaust's tailpipes. they clear the massive Spintech XL's just fine, but they protrude right into where the tailpipe would hookup and it's protruding right into the area where the band clamp would mount so denting it isn't a possibility. What I may do is weld the tailpipe section to the mufflers so that I can dent it then, but I'll deal with that another time.
There were no instructions for the rear bar and I believe this is because the kit was never designed for the B body, it's just an A body bar I believe that they sell for the B body because it can be made to fit . On most other chassis mounted sway bar kits i've installed there are very specific measurements on where to mount the end link brackets so that the sway bar is centered and the end links have the correct angles. for this setup, I'm just winging it and trying to get the bar as parallel to the ground and the end links as vertical up and down and square to the bar as possible.
Hopefully with some luckI can fire the car up, have it tuned and get it road worthy by fall so I'll post a further review on how it is all working on the road then.
