I believe you have what I'm looking for good sir. I took a pic so you could see the length of the yolk...A 52.5 is the one, are you willing to sell yours.
Yes if you can use it, I run a gear vendor over drive in my car and don't think I will need the old drive line. You live in Washington State? and what part if I may ask I lived in Tacoma area most of my life and have lots of family there.
