Putting last touches on my Phase 1 supercharged motor and am missing the correct accelerator return spring, the parts catalog lists the number for a supercharged motor as B7A-9737-E, .68OD-3.60 long 32 coils that also fits a car or station wagon with fordomatic. Does anyone have one they would sell or know where to find one and the bracket that it attaches to? Thanks, Randy
