I just checked the napa on-line shopping for a 65 GTO , they have the p/s gear box quick ratio listed as NSP88277060 same as my original post. I guess I could go to the store and talk to them. I did search by part number also 27-6509, no part listed??

I've read about all the boxes that you can get out of the bone yard and change to style fittings and new pump discharge fitting/flow control valve. I think the turning radius for the correct box is 43 degrees or so each direction. I could get mine rebuilt (stops removed) but I'm looking for the easy and fastest way out.

Wish I could edit my post?

Anyway I found my receipt for the box I purchased 10/13/05
Advanced Auto Parts number 27-6509 and it is a Cardone box. Guess it's hit and miss with them on the correct stops.
