S13 HICAS steering rack installation

[Kenji001]

My S13 has free-play for steering. I already replaced the two steering rack bushings, and installed TEIN tie rod + tie rod ends. Now I have two options:

1) Replace the non-HICAS steering rack with S13 HICAS steering rack for quicker ratio

2) Replace the steer column bushing

Have any of you installed the S13 HICAS steering rack or steer column bushing? Is that really hard to do? Is there any installation guide online (I googled, but I couldn't find anything)?

Thanks!

Plenty of info online, even on here. The bushing is way easier with the column out of the car but doable in. The rack itself is cake from under the car.
