C10 Nation!

I rebuilding the entire front end stock. Rebuilt upper and lower control arms including shaft assemblies. I have installed both lowers and lined up the rivets with the forward divots on the shaft assembly.

After installation I noticed that there is 1/2” difference between the two lower control arms in relation to the crossmember. Is this a problem? If so, what is the solution?

Please see pic’s.
