Jac,
Thanks for explination above, understood.
I don't have my car here but if no other SPF owner or dealer responds to questions I will when my car is back home.
In meantime: I believe the rod end bearings are in fact slot pinned to the rod end (see pics from Chuck and Lynn in their posts above) and note the "bump" on rod end housing facing rear, looks like a pin head to me), also I believe the "washers" are not collared over the bias bar pedal sleeve but in fact that there is a brass bush in the sleeve and the washers float independant (OD of bush vs ID of pedal bar sleeve allows required float). I recall my inspection of the assembly in my car to have shown a slight space to allow the bias bar to pivot as required fore to aft but, the SPF design does a good job of keeping the bar in a narrow horizontal range...Also as noted if one of the masters fail the design greatly minimizes a droop in the bar that would restrict stroke.
Anyone else?
Steve
