spyder gears in sure grip

[Derrick Brown <63max426@xxxxxxxxx>]

hi all,

i have a 742 cased clutch style sure grip unit.

i want to repair the sure grip unit itself (slipping).
i know i can get the clutch kit for it.  does anyone know where i can  
get replacement spyder (inside the unit) gears for it?  looks like it  
was let go too long and at least one gear got chewed.

thanks.
