I need to mount early 58 female hood latches. Currently, there are no correct mounting plates nor correct holes for these latches (a 60 body on a 58 frame). Would someone be able to provide some measurements, possibly using the bumper screw or back or side edges of the latch in reference to the back and side of the firewall? Also, if not too much to ask, the location of the openings in the firewall for the cables to exit. Thanks.
