<VV> Shift linkage linch pin

[Cash Case]

Hi guys-
I've rebuilt my transmission with the help of ones of our 
club members... thanks Bill!  He was a great help.  He did a great job 
of explaining what does what where and why.  Transmissions have always 
been voodoo to me.  

Anyway, I've got my '65 out of the garage finally, but I can't find the linch pin that connects the shift linkage to the shift rod that comes out of the transmission.  Can anyone tell me the correct length and diameter of this pin?

I want to drive this thing again.  ;op

-Thanks in advance!
