Schick G5 loose head

[Jayaruh]

I picked up a Schick G5 at my local antique shop a while back .When I got it home cleaned it up and sanitized it I loaded a blade and noticed the head is loose and the spring was jacked up and not fully between the post .I moved it over and gently tried making the top of the spring even, looked ok did a shave it got me good ,the head was still loose on the right side . What's the go to fix for this problem? Thanks . 

I am thinking that if you used some needle nosed pliers and clamped on to the bottom of the spring you could gently nudge the spring up with a twisting motion. It looks like it has been bent down somehow. It probably wouldn't take much.
