I'd get a different rear end. If I read you right, you want to try to narrow the whole frame from just behind the front cab mounts? That's crazy in my opinion. Everything has to be modified. Keep digging for a rear that is closer in size.

I haven't worked with the swap, but can't you run a different rim? Your answers have to be in the Bolt somewhere. Have you talked with Grigg?
