Power to Manual steering box ..shaft / adapter?

I did it to my 69 Dart about 15 years ago and haven't had any problems with it yet. The only thing that will get messed up is some nylon plastic that is in the collapsible shaft. Not a big deal!
I have the adapter that you need listed in the parts for sale section, and so does Firm Feel,, they want 125.00,, my new not used firm feel part is less,, if you can't find the ad send me a mesage and I will find it for you, I can also send a photo of the same adapter used to fit a power steering shaft to a manual box.
