I think I found my solution. Granted the largest I can go with this method would be 10x without cutting and splicing but I emailed the following via their form online.
I was wondering if you folks have any molds for a spacebar over the semi standard size of 7 units? I am looking for a dark gray to black spacebar in PBT in any size between 10 units and 15 units. Any help in this would be greatly appreciated.

Thank you for the request! We have a variety of spacebars over the standard
7 unit size - you can check out the various sizes on our datasheets here:

So I head over there to that link and clicked on the link for the DCS family as I think that is the profile that we commonly use for our GB's and lo and behold they can make space bars in the following sizes 4.5, 5, 6, 6.2, 6.75, 7, 8, 9, 9.75, and 10. Also according to this page they can be made in ABS and PBT. Now the question is will they let me purchase a couple of them.
