The '39 had six-lugs when it was new. The answer is probably yes you can swap, but without knowing exactly what he has it's difficult to say with certainty.

In the 70's I used early 50's Chevy car hubs to convert the front of my '41 Chevy pickup to five-lugs. Its not hard, but why not convert to front disks if you are going to do all that work?
