Alright, here's the deal. I'm building a new car and have a front suspension question. I am planning on using '78 Caprice spindles on a metric car b/c the longer spindles change the angle of the upper a-arms and, consequently, lower the roll center of the front-end. The problem with this application is that you have to add a ton of shims at the upper control arm to get the correct spindle angles.

I have heard that '68 to '72 Nova lower control arms will bolt on to a metric car and are longer than the stock lower control arm. If this true, than that extra length would help to correct the angles w/o all the shims plus it would widen the front track just a little more.

Has anyone ever tried any of this? Did it work? Also, do any other cars interchange with the Nova lower control arms?

Actually the taller spindles should raise your roll center (but that is a good thing) and have also have a greater kingpin inclination (10 vs 7 degrees, better for dirt). Don't know about using Nova lowers (though I seem to recall they swap left for right when putting them on a metric car), but I Do know that you will have some bump-steer issues to sort out.
Get Steve Smith's Latest book on IMCA Modifieds (#280?) It has a lot of info (including quantifying and correcting bump-steer issues) that will help you re-design your front geometry.
