12:05 Garage- ’70 Duster build

Yes, still have the 450lb springs. That's another thing that Benjamin will evaluate for me. I don't want to go too stiff on the spring if the bar can make up for it. After all, I still street drive this thing and I wouldn't want to make it so stiff that it becomes unpleasant. I'm going to scratch make everything for the sway bar and I'll detail it all here. I figured out a relatively "cheap" solution. The base of the design will be a larger diameter tube that spans across the current mounting points to add some rigidity. That tube will have bushings in the ends that can be swapped out to match the diameter of the actual sway bar tube. I also plant to have a few holes in the arms so I'll have some finite adjustability. I'll also ditch the poly bushings and go with heim joints. I'll have to see if those end up being too harsh for street driving. If they are, I can simply make up something with a bushing for one side and swap it out when needed.

Interesting! Are you still running the 450 lb/in springs up front? I know I bought a set of 1.18's for my Duster, even on the street once I started running the Falken Azeni 615K's I was able to bring back some body roll that wasn't there when I was running the harder KDW2's. Your wheel rate at 300 lb/in may still be a bit light.

The NASCAR style splined sway bar is probably the way to go for competition, you could even get a couple different wall thicknesses if you wanted once you get the construction figured out for the car. Some of the kit cars had a similar set up with the splined sway bar. Definitely interested in what you end up doing, I've considered going that direction myself but the Hellwig's I run are just fine for the street for now. The '73+ K frame and the bar running through the K makes a straight splined bar a little entertaining to set up. Speedway sells some splined sway bar kits, they may have something that's in the ball park to start working from
