Engine bay support bars

Just having a poke around and noticed that the two support bars don't appear to be fastened to anything whee they disappear above the engine!

So, what do they do, what do they fasten too and how do it do it?

Thanks as always

There are two long bolts on the engine cover that go through the ends of those bars.

I have an MGF and someone suggested it might benefit from fitting some of these.

Is this feasible and if so is it a serious improvement? If so I assume I would have to get a second hand pair - where from?

Ah, thanks Bob. That makes sense🙂

I believe this comes as part of the VHS torsional stiffness kit https://www.vehiclehandlingsolutions.com/products/#mgf-body-stiffness-kit which looks good value.
