Rack and pinion steering.

This has me curious. I’ve never mapped out factory a-body suspension in a software, but for those that have, what is the ideal location and length for a front steer rack/steering arms, and still get good geometry for Ackerman, bump, and toe? I used suspension analyzer when designing the front end on my ‘69 and it took days to get that dialed in, and I still paid an expert to fine-tune it. That said, with available suspension software, the ability to get different length racks, and produce a steering arms, what does it take? I’m kind of surprised it hasn’t been done yet, and maybe it’s been studied and tested and that’s why we have coil over kits with M2 knuckles. Would love to hear from those that have actually run this through software, or mapped it out.
