Oversized lower ball joints

[craigg1]

Had some work done on my front end today, 67 C10, but front suspension swapped with a 72. Anyway, all went fine until installing the lower ball joint on drivers side. The ball joint would not seat right and was told the Lower control arm needed replaced.
I have read where some people say to tack weld the LCA. Others have mentioned using an oversized ball joint. Has anyone used an oversized ball joint....and if so did that fix your problem? Thanks.
