Width of the K Frame

I just bought a 47 Dodge and will most likely remove the 47 front end and go with something more modern. Someone told me a friend used a F/M/J complete front suspension/K Frame on his a late 40's Chrysler and it was nearly a bolt-in. Soooo, I'm wondering what the width is of the K so I can compare it to the frame of the 47. I like the idea of the one complete unit with suspension and K . Or, if anyone has done such a swap, I'd love to hear about it.
