[corvanatics@corvair.org]

i am working on a 65 greenbrier deluxe  , putting engine etc back in shape.  
today while jacking it back in i noticed the right aframe has punched out area 
for the 64 style rear spring attachment pin mount. the left does not have 
this or my 64 greenbrier or the 63 rampy....i took pictures. anyone ever put a 64 
type rear spring on a fc?  this will be a group red candidate when i get time 
to write the sad long story. regards tim colson
