<VV> LAKEWOOD PROJECT question

[N2VZD at aol.com]

Does anybody know for sure if the body is heavy enough without  powertrain 
in it to jack crossmember up for rear spring  installation?      I don't 
want to find out after I  unbolt the shock. I may try it by jacking it .
I would like to do it before I paint underneath  which is way  before 
hanging the motor etc back in . I have it up on jack stands for floor cob  job 
,brake tubing , wire harness, and gas tank repair.
  The springs in it now have those cast "twisties" in them.
 I am having so much fun!
Regards, Tim Colson
