Here's photo of my vintage LynxB rear shocks and Z-bar. You have the mounting points for the Z-bar blocks.
Everything above the frame rails is much different than my LynxB, but it's still likely a LynxB. I've been told by a few Lynx guys than mine is likely a earlier example of a LynxB.
Also, I highly recommend adding "Maggie Bars" nerf-bars when you repair the frame. In our vintage FV group the VSCDA, 100% of use run them and their use is spreading quickly across the country.
Good luck with your LynxB, if you need any more detailed photos just ask.
