70's frame out of square by 3/8"?

[jon90]

I'm currently working on my first project truck. I have the truck stripped down to the frame. Question is the truck was out of square by 3/8" before I shortened the frame, and is still out by 3/8" now that I have it shortened. Is this worth bringing to a frame repair shop to have it brought back to perfectly square? seems like an old truck might have some tolerance but not sure how much is too much? Im from a small town not sure there are too many shops around with frame rack and dont know if it worth a trip to the city with the frame in middle of winter for 3/8", any info would be appreciated.
