Gotcha... here they are. 2 are on each side near the outer top / side of the back glass. Its like a seem where 2 fiberglass parts are bonded together and u can see through the paint that the seem is there.
THe other is on the very back lip of the subtle fin that the 73's have. On the rounded part of that fin you can see some cracks running parallel to it.. kind of hard to see. I can't tell if its the fiberglass itself that is brittle or dry rotted or just the paint.... Known problem? Hard to fix for a novice? I haven't bought the car yet and I'm trying to research BEFORE i spend cash on a mess!
