someday someone will make a 8.75 twin with a 7.125" nose and tail and a 14.125" wheelbase...hopefully. I'd settle for even 7" nose and tail with a 14.25 wb just as long as it's 8.75" wide. Just putting this out there in case manifest destiny works via text on a forum. For now the girl 8.5 twin I just ordered will hopefully be alright even though it's the narrowest board I'll be skating in years.
The Ishod 8.75 twin does have a longer wheelbase, but what trucks are you skating?
Only because I have another option for you, but it won't work on Thunders - already drilled in the middle, but as I have tried it and it is working on both Indy or Venture, you can drill the baseplates in 1/4" each which gives plenty of gap in metal between original holes and new holes, as well as still keeping the front and back bolts away from the pivot point, so will not catch on nose / tail slides.
On face value, people would ask "Who would ever drill in their trucks?" but as per the Venture thread, Ishod himself is skating Ventures that have been drilled in, so this would easily work on Venture or Indy to make the Real Ishod 8.75 deck into pretty much what you are wanting, in terms of wheelbase and length of kicks.
All you need is a basic drill and a 5 mm metal drill bit, a little effort and getting things right and there you go, trucks that you can use on any and every 8.75 twin board, only having to drill them once, not having to drill the deck, can always still use it in original holes if needed too, so you have a fairly simple solution.
I would recommend trying to drill an old baseplate first, going slower rather than faster and it was a lot easier than I first thought to get through normal cast baseplates, with a friend also drilling out forged baseplates too, so it works on either there.
If drilling out Venture, they only have four holes, but if drilling out Indy, go with a four hole baseplate, not the six hole baseplate, which is 3/8" difference and the bolts will sit out past the pivot cup area a little too much.
That is my experience and even though at first, I thought that would not be a good idea, it does work, the holes do not break through, the trucks hold and it really does open up a completely different option for one or both trucks on some boards that might not work quite as well with just the usual hole pattern on existing trucks.
