My high cap 130 TD5 has this rattle (sounds like spare change in a tin) at
exactly 83km/h. I have wrote about this a while back in this forum but in
the meantime I have checked all the heatguards around the exhaust and could
not find anything. Just recently I made a new observation, that the rattle
even appears if I just rolls down a hill with the engine on idle and exactly
at 83km/h the rattle appears without any engine vibration going on.
Could it be from the drive shaft? I have checked all the little balance
platelets which are glued on the shaft and they seem to be all right.

Try rolling down hill ( if the road is staright of course) with the engine -
off occasionally a baffle will become loose in a silencer box it is (
sometimes) just possible to hear it if you put the car on a ramp and shake
the system vigorously , and even as I found out it can happen in a new
system. It sounds much as you describe another possiblity is a stone trapped
I have heard drive shaft problems and they tend to a knocking sound rather
than a rattle.

I had something similar at around 50-55mph (almost exactly the same speed)
on my 110 when I first bought it, turned out it was the handbrake cable
resonating against a bit of the seat box bodywork! Worth a look, maybe?

Also worth popping underneath with a universal screwdriver (a.k.a.
hammer) and tapping the exhaust boxes and other tappable things to see
if you can find sommat that makes a rattling sound. Watch out for
**** falling into the eyes.

With my 90 it was the heat sheild on the exhaust pipe that had come loose
and was rattling. Needed a new bracket as the old one had stretched too much
to tighten.

I have a very similar kind of a rattle on my 110 first thoughts exhaust
heatshields or similar but I do like the handbrake cable idea my noise
sounds to be in that area! another thing to check could be brake disc back
plates or you could try the usual turn the radio up method
