Mike, its UPC M13. I did read that section on 3 speeds, I did not see anything about floor shifts for standard Saginaw 3 speeds only column shifts
You should look again: "It was column shifted unless a console or RPO M11 floor shift was selected."
M11 was the floor shift option. It took a standard M15 trans and made it floor shift. $10.55.
I don't see it in the AIM.
Anyone ever seen a window sticker for a pacesetter car? L6 window stickers are rare to begin with....
