It says on the webpage significant modifications are required to mount the fiberglass bumpers intended for the 240 and 260 cars on to a 280z. Have any of you successfully mounted those fiberglass bumpers on a 280z? If so how "significant" were the modifications?

I have not had to do this, but from reading other's postings in days/months past, it involves fabricating brackets and a bit of ingenuity.

Brackets are available. I believe Eiji Hosomi sells them. His website is Datsun Spirit. He doesn't list them on the site, so you'll need to email him.

I've done it. The brackets are the easy part. You have to drop the fuel tank to get the old bumper shocks out, then you have to cut the rear filler panel off with a grinder and shave the rear. The you have to weld in sheet metal to cover the big holes in the rear apron, you also have to grind off about 10 spot welds then hammer them in a bit and the use your body filler. It's not difficult if you are comfortable doing that stuff, it took me about 20-30 hours.

I can vouch that it is a royal PITA to remove the old shock mounts!! I did that part...but the bumpers were too rough for me to attempt to prep & paint them myself so I employed a local bodyshop to fabricate mounts & prep, paint & install them. It was $800. Since then http://www.zccjdm.com/ has started making the mounts. I also didn't know they could chrome the fiberglass 'cause I might have done that. The holes in back are barely noticable (where the old shock mounts were). All in all I am really happy I did them. It did raise my car up about 1-2" though. Which was my excuse to get Tokico springs & struts. My 260 is a late one so its very similar to a 280.

Nissan used to make big rubber plugs for the cars sold outside the US but still had the stock rear apron.

I put them on a 260 that I removed the shock bumpers from to fill the oval-ish holes. They were sourced from Nissan in the UK.

I'll try to find the part numbers.

I used the zccjdm bumper mounts to install 240z bumpers on my 280z. 30 Ounce is right... removing the original cow catchers and bumper shocks is not for the faint of heart. The zccjdm mounts work good, but would have liked a cleaner solution to the side mounts on the rear. I fabbed up some myself for a temporary fix. Does anyone know if there's a better way?

The way to do it is to fill the old rubber side mount hole, then drill a hole directly behind the 240z side bumper tab. Use large washers and the bolt goes all the way through and is secured by a nut and lock washer on the inside. Be very careful, the hole on the right side will be very close to the fuel tank filler neck, and its a real PITA to get that bolt in that tight space and tightened up. I had to make the hole slightly larger than the bolt so that I could work the bolt in at an angle to get it through. The original mounts use a rubber pad/grommet that will keep the metal tab off the bodywork.

I will add one thing. Make sure the rear mounts and bumper is right were you want them

before doing the sides. Put a level on the bumper at the rear. Then use a level on the bumper side before marking the holes.

Thanks Gents! I can guess this is not one of those times you get multiple tries at poking holes in the side. Thanks for the tips.

Has anyone tried to put the carbon fiber bumpers for a 240 on a 280 that MSA sells? I would think it would about the same. just checking to see if anyone has thought of this.
