The thing I found (Or didnt find?) using the search function for the Z bumpers is noone has a good description of "HOW" they physically mounted the damn things to the 280. Yea, lots of people say "its been done, ask so and so" or "Ive done it" or "Do a search" but not one person has really explained what is needed to do the swap. Or atleast I havent found it. I just assumed everyone knew what they were talking about, ordered the parts I thought I needed, and then modified them to work. It isnt a complete bolt on swap but it isnt impossible either. I had to make custom brackets for the rear bumper, mainly because the originals I got were less than straight and I also wanted to tuck the bumper in close to the body. The front brackets (70-72 only) worked but I had to do some re-shaping to get them to align properly. I used the front spoiler for a 280 so I could keep my 280 turn signals but the 240 lights will work if you use a 240 valance or spoiler (preferably spoiler to save more modification) in the front. On the rear, you will have to remove the filler panel and re-paint the area. You will need to remove the fuel tank to remove the shock absorbers also so you can mark, drill and install the bolt on the right side quarter panel. So yea, maybe my Z isnt up to the concourse some Z snobs demand but it looks damn good and a hell of a lot better than the big crash bumpers. Not to mention, I have fuel injection and a/c that work! Now its time to get out of the z car club. I am really getting sick of car forums, can you tell?
