Just got an 87 Z24 smashed in the front and looking to restore it.  Looking for a parts car or else the following:  blue interior, seats & all.  Also front bumper re-enforcement and radiator support.  We are in southeastern Wisconsin....so looking for something around here.     
 
Thanks!  Can't wait to get it going!  Had a 87 Z way back when, loved that car!
 
Try the 1st gen section?
