Firing pin replacement

[Ole Scratch]

Need some help.  The fine folks at CVA sent me a new firing pin and spring.   Thanks to them!!  Now I need to figure out how to put it in. I have the older rifle.  There is one screw on the right hand side of the rifle.  How do I replace the pin?  Any help?  Thanks in advance.

Anyone??    I unscrewd the screw and the transfer bar slid down but not enough for the old firimg pin to come out.  Anyone know what I am doing wrong?  Thanks
