I guess I should have clarified, that I'm wanting to make a spacer plate, not an adapter plate..... it's getting late!
And as far as the rear end swap, I'm wondering if it can be done, is it a big job as far as re-setting the gears, and ripping the rear end apart, or is it fairly easy. I've never taken a rear end apart, but I'm fairly mechanical so I think I could figure it out. 0
