Actually, this is pretty easy with a VNA.

Subject: Re: [PSES] Chassis Bond Impedance Measurement
Jim, as others have suggested, this is a pretty touch measurement to
make
with any certainty using conventional means.
If the two modules are operational, it's possible to measure the HF
voltage
difference between the two pieces of metal structure (or connection) with a
differential probe connected to a spectrum analyzer. You should be able to see
in real time any effects at reducing the bonding impedance.
If the bond in question is passive, you might try a transfer impedance
measurement such as used to measure EMI gaskets.
