I have a 1978 280Z that I'm putting 1974 260Z bumpers on. Do I need to replace the mounting shocks in the rear or can I use the existing mounts? Please advise any other changes or mods I have to do front and rear.
YES! It's what I run on my 73 AND my skinny-bumpered 74!
Had to order the hole plugs from Japan to plug the holes in the rear apron on the 74, as well as relocate the horns. But the 73 took them just fine.
