Placement of axle

Hi all After 5 years of wanting to start my tear drop I finally got started.
I had the frame welded up for a length of 114 7/8.
The welder placed the axle 52 inches from the back frame member and after reading other sites I am worried that it was put too far ahead.
It wouldn't take much to cut off the front axle bracket and place ot further back.
Any comments?
Thanks
