67 Nova rear suspension.

[kadettcqp]

I will within the next month or to be purchasing shocks and sway-bar for my 67 Nova sedan, but even after looking for quite some time i have not been able to find exactly what I am looking for.

The car has a mini tub and is sitting on a single-leaf spring, which is running inside a "slider". I have mounted the sliders but i have not purchased the springs, they came with the car when I got it, I therefore have no idea about the rate of these springs. They however, mounted without shocks, seems quite soft. I therefore suspect that I would need a rather "hard" shock to stiffen up the suspension.
The car will be used primarily on road but will both see track and drag use. I can live with a very stiff suspension, but would hate to have it too sloppy. Can anyone point me in the direction as to what I should be looking at, that is not only a drag-shock and that could help stiffen up the rear suspension?

Secondly I would need to look for some kind of universal rear sway-bar since the car has a mini tub I would suspect that standard 67 Nova sway-bars would no longer fit?
