Cable lengths needed

[MNtriple]

Hi everyone - I'm in the final stages of an R1 front end conversion on an xs 750. Even though I don't ride a 400, wondering if I can have a little help here. Can anyone tell me the lengths of the xs 400 tach and speedo cables? mine are now too long and I'm sure the 400 has the same ends as the 750 / 850, but I would think the 400 may have shorter cables.

OR, does anyone know a way to shorten these, or a source for custom length cables
?
