From the hardware book it appears the same hardware as the Cabriolet. Special nut for the shaft, flat washer, Grommet 48-761370 (flat rubber or leather same OD as washer and same ID as the shaft) On the interior is the spacer 48-761424. I believe that is all.
Ford used the spacer with different lengths and finish on a number of cars. If you can find a longer one you can whittle it down to the correct length and have it chromed. It is made of white metal. The wiper shaft slides through the hole in the center and the step goes against the motor and holds it in place without any attachment hardware. The two small **** on the other end go against the wind shield frame. The one stem nut (5/16-32 with 7/16 hex) holds the assembly together. I believe Kent Jaquith at "Clean Sweep" has the spacer [FONT="]Kent Jaquith[/FONT] [FONT="]Clean-Sweep[/FONT] [FONT="]2633 SW Obsidian # 15[/FONT] [FONT="]Redmond, Oregon[/FONT] [FONT="](541) 923-4319
