Power Steering Conversion for a 66 Dart 270

Hey all, I'm brand new to FABO and excited to be here and learn/share. I just recently bought a 66 Dart 270 with a 4spd manual and a 273. It doesn't have power steering, although I believe it was an option for the car back in the day. I would like to add power steering to my dart but I am having trouble figuring out exactly which kit to go with.

I'm finding parts galore for 67-74 Darts, but it's hard to find anything for a 66. I know that many of the engine parts are compatible with later years and/or the 318/340/360. I just am not sure which power steering conversion kit will work for my 66 with the 273. Can anyone point me to the right kit?

Thanks everyone!
