Ken and I compared the dimensions we measured which means the new chain sliders are the same as the ones we have but the swingarms aren`t.
Yours is a 907ie swingarm while mine is for a P750/906.
The two have a different chainline. I had the suspicion it would be so but I thought the chain sliders would be different. But if you look at the pictures the bracket the slider mounts to is offset more inwards on my swingarm.

As that side nose is in the air on your swingarm while I had to cut off mine I`d assume the chain sliders for the 907ie and P750/906 are not identical and you have one for a P750/906 while mine is originally for a 907ie.

PS: another small difference: some are cut off flat in the front like mine, others aren`t
