If the sidelock fits good with crack open like it is, I might not clamp it. One problem is old wood shrinks over time which can comtribute to it cracking. You could put a clamp on it first to see if both sidelocks will still fit.
After glueing, you could also 'staple' it. Where the crack is the most open, probably a one inch staple could be installed. I use coat hanger wire; the ends bent 90 degrees to go into the wood but not through it. Drill holes a little oversized. I then use a round tip cutter in my Dremel to make a channel for the span of the wire so it is flush with the surface. When drilling holes, don't forget to allow for the depth of the channel. 'Dry fit' the staple first. Put Aacraglass in the holes and channel and install the staple and scrape off excess with a straight edge. Wouldn't hurt to also put a staple between the hole and the end of the lockplate recess.
