learning... question about rack and pinion

[RallySnake]

The critical thing is that the pivot points of a steering rack must line up with the inner pivot points of the upper and lower A arms. If they don't, you will have very bad bump steer problems.

You should post some pictures of your front suspension in hopes that someone will be able to identify it and help you find the right rack. If it's a Mustang 2 suspension, then the problem is easily solved.

Rally Snake,
the kit came with OEM lowers, but does not have uppers. I've been reading on here about the different widths of factory vs. aftermarket, and upgrading, and think (still have to do my research, so correct me if I'm wrong or you have a suggestion) that I will use Heidts package (link below) and QA1 coil overs, after I lower the upper mount by lowering it 2.5". I'm reading about the issues ppl have had with clearance, travel, shock/struts making contact, diameter of the bolts, not matching, geometry. I'm really hoping to NOT have to do a ton of fabrication to the frame. The kit is still in storage 400km away and I'm waiting for good weather to pick go pick it up.

You might want to reach out to Flaming River. They make racks for everything.

RS is spot on there. The rack must be mounted so that the pivot points are reasonably closely aligned horizontally and vertically with the inner pivots of the lower arms/wishbones.
Of equal importance, the tie-rods (rod-ends) need to be parallel - or close to it - to ensure zero (or minimal) bump steer.
