Here you go a simple and very strong way to bolt your 400ex nerfs to you R
First I took off the stock pegs and cut off the mounts to leave just the flat plate.
Second I took the 400ex nerf mount and mocked it up to the stock 250R mount...I was just going to weld a tube to it but after further investigation I needed the extra width.
Then SKEET a little wire...There not my best welds had WAY to much whiskey that night. But they are plenty strong
And two shots of the finished product. I am going to take them back apart.... weld up the extra bolt hole smooth them out and shoot them with some paint.
If you have any questions or would like more pics let me know.
