<VV> Upgrading from 3 speed to a 4 speed

[Ebarr19 at aol.com]

I have a 63 autocross car " The GEEZER " I put the crossleaf spring on it 
and it worked fine for normal driving, but during autocrossing one time the 
leaf spring shifted forword. I installed the proper 64 diff-case and all is 
well. I also use the 63 springs all with one coil cut off, as you can tell 
from the Convention autocross times it does well for a a low performace 
-early-automatic in IS-1 class.
