Yours appear to be the non wrap around version found on all 67's and most 68'sHm, none of those look like my shock towers.
If you can make it out, mine don't wrap around at all. You can see the edges sticking out.
Don, can you tell from my pick if mine have the extra bracing or not?
Over at the SAAC forum they talk about two types; an earlier welded reinforcement and then the later wrap around one. They even mention cars that came thru with bracing on one side and not on the other.
