1969 Dart Pro touring daily driver **Crashed**

I put a Borgeson steering box bought from Bergman.. i had to add a PS fluid cooler cause I would lose assist when headers heat soaked steering box. Also had to pull column out and re-orient steering wheel cause splines from steering shaft to box aren't keyed. Now that its all sorted out it is super nice. It does deliver on that modern car steering feel. And my PS is completely silent zero noise at all.

I remember reading about your issues but didn't know that this was the cause. Any idea why this was not an problem with the original box, or did you go from manual to PS? I luckily got a cooler from Bergman but will certainly look out for similar symptoms.
