I'm new here, but had to make an account as I'm dying to figure out why I keep seeing photos online of 280zx's with what appear to be stock bumpers without any "bumps" for lack of a better term. Almost all s130's (including mine, 1979 2 seater) seem to have two bumps on both the front and rear bumpers, however these few that don't (I think) look much better. I also think the rear bumper on these "flat" versions might be smaller (protrude less).
I have a theory that this may have something to do with the cars being JDM/RHD/not North American models but I haven't found anything to back this up.
If anyone has an explanation or a place where these bumpers (or similar) can be purchased I would love to hear!
I have attached some photos that I've found on the internet of the "flat" examples.
Thanks! - Jim
