SPORTERBOY, A chopper huh?

What lowers do you have? Lowers are not too expensive, so, if your going to go through the effort of building a custom then take your time and spend the few extra bucks to make it right the first time . I’m on my second home built custom, I skimped on the better parts to get the project on the road, then I find myself re-buying the right/correct parts to make it right.
15 over seems like an awful lot for 6” over down tubes & 40 degree neck. IJMO...
I’ll assume your going to use a 5 or 7 degree tree to correct your trail. With a 40 degree neck, 15 over tubes and the degreed tree, your looking at a real long cycle,,, your well over 50 degrees of rake. If you would like to discuss this any further you can IM me.
Oh yea, you can use all the same guts when replacing your tubes…don’t know what you mean by making longer spacers.
Good luck.
