Cab to bed alignment.

[desert-rat]

Picking up a '72 long bed next week. New paint, rims, tires, built 350 and some other stuff. The cab to bed gap is suprisenly perfect. But I noticed the cab or bed sits a bit off to the side. It's not noticeable unless you're looking for it. If you're looking at the truck from the front, the cab sits to the left or the bed is to the right. But I noticed it because I was checking gabs and lines when I was checking it out. I measured the wheel base, exactly 127" on both sides. Is there
side-to-side adjustments?? Thanks.
