Sure Grip Cone Type Spider Gears.

Hi Gents,
I'm desperately looking for the 2 Spider Gears for a 489 Cone Type Sure Grip. Cass at Dr. Diff says these parts were never reproduced, as the cone Sure Grip was never intended to be rebuilt.
The Gears have 10 teeth, where as the non Sure Grip have 11.
I thought I would ask here at the Mopar Nerve Center, also someone willing to ship them to Germany, at my expense of course.
Thanks for looking.
Cheers. Gaz.
I have a pile of that stuff out in the shop. I will look tomorrow, but I cannot promise anything.
