Will This Work???
I can't tell if you're talking about having the hub for an LS_ disc changed out to 10-spline or using an 11" "old" disc with the LS_ pressure plate. Be careful on the i.d. and o.d. of the PP face, making sure it has correct friction area with the disc. If using old disc + LS PP, triple check the PP has clearance for the disc hub.
Mock up your extended pilot bushing and try and give it enough coverage of the input. Don't just hammer it into the crank as far as it will go if it can stay out a tiny bit and better support the input.
Napa has a really good TO bearing catalog (if you're patient) if you haven't found the right one yet.
Hopefully there won't be any issues with where the disc rides on the shaft since this isn't supposed to work according to everything I've been reading over the past year. Wish me luck...
