Jim you are asking questions that might have multiple right answers, depending on what you are trying to accomplish.

Why do you want to do a frame swap?

It is much easier to change rear axles than it is to narrow a front suspension. If you look at Grigg's pictures you'll see he has narrowed a front (twice I'm aware of) and if you read AD-engineering carefully you'll decide his goal is new suspension under a stock looking truck.

What is your goal?
