<VV> 63 into a 64 options

[N2VZD at aol.com]

i did see an adapter made that bolted on the lower diff bolts and came  
under the case to hold the center of the spring.
only options i would consider is 63 convert rear springs , or best way: put 
 a 64 differential in it, put the 63 guts in the 64 case , or rebuild the  
64.  try to stay away from a cob job.
 the 64 was the best year in my book , so i am swayed a lot towards  
keeping it 64!
