Using third person character for first person body issues, need help

I resolved this issue by using the First person blueprint and copying over the 3rd person assets into that. Attached the full body, and removed the first person arms and weapon. You could also go the other route and create a camera range limiter to only allow the head to rotate 90 degrees in either direction. But the main issue with the 3rd person blueprint and a body is the mouse drives the movement direction. So you wont get a turn in place whereas the first person blueprint gives you body direction based on mouse look.
