leaf spring center pin too small, will it matter?

Just installed Tom's 3.5" leaf spring lift in the rear. Started at 8:00 finished at 12 noon.
Did find the center pin head on the new springs is smaller in dia than the stock center pin head. Is this going to be a problem?

As long as the center pin will keep the springs in place on the perch and the u-bols are on tight, I don't think it should be a problem.
I had a similiar case where I used a different bolt and there was that much of play so I left it.

Should not be a problem.
