Owners
of older Morgans often inquire where they can source replacements for
their
over- riders, a popular Morgan option from the 1950s-1970s. These original
overriders
are very different from those used by the Company since 2002 when they
were reintroduced with the LeMans '62 series. Unlike these recent
overriders, the originals are not aluminum, they are chromed steel,
much smaller
and contoured. Many owners of much later cars, retrofit these originals at the rear and
remove the bumper
(the original overriders fit without any modification to the
later
bumper brackets). The overriders (12 oz each) weigh considerably less
than the later stainless bumpers and have a pleasing aesthetic effect.
For many years, the accepted lore was that the overriders were sourced form the later version of the Morris Minor. Sadly this is not true. Sad.. because the Morris Minor is a well-beloved car still and there is a constant supply of relatively inexpensive parts for it because of the level of demand. The Morris Minor overriders are indeed shaped exactly like those fitted to Morgans BUT the bracket welded in at their back is set at the wrong angle for a Morgan. If the bracket is removed and repositioned for a Morgan and re-welded. the process ruins the chrome finish. If they are found in a state where they need to be chromed, then the welding won't cause further damage.
model prices were not lowered, only raised. But Morgan bumpers/overriders, aside from the North American verisons attached to a airbag mechanism, offer no meaningful protection.
Retro-fitting these large overriders to earlier cars looks decidedly odd as the earlier cars are much slimmer than the new models. Owners of models made between the two overrider eras normally choose to fit the earlier overriders at the rear.
MORGAN BUMPERS & Overriders

article. Read on. 
Yet Morgan
does not change the placement of batteries (or much else) for LHD cars. They are
placed behind the driver, adding to the extra burden on that side.
Add that to the fact that later cars (post 1998 on Overseas cars and post 2000 on others) have evaporative emissions systems. To
fit the sollenoid valve on those systems, Morgan shortened the width of the fuel
reservoir on the RIGHT. The reservoir capacity went from 12.5 imperial
gallons to 12 US gallons or (appr. 52.5 liters to 44.75 liters) a
difference of the other 18 kilos or a total of 145 pounds. In other
words, to balance the car, you must find a life-partner of that weight.
(chortle!) Alternatively, you can move the battery to the right side
and the tank there as well. (sad sigh)
