The 5 mph impact standard and minimum bumper height
regs came in force in the US and Canada beginning in
the late 1970's and continuing to date.
Bumpers had to placed higher than the British norm (15
in. center line in 1984) and they had to be able
withstand a greater impact than than the MMC
manufacture.
(Other strengthening and safety modifications were also
required. If you are interested there is an article
entitled Made in the USA off the Plus 8 page at the GoMoG site you could read
that includes most modifications).
The bumper treatment front and back varied from each
of the 2 US and 1 Canadian agent. Some of the bumper
support/brackets designed were less than sublime. One
for example, was so heavy that it would take two men to
lift one Morgan bumper and its support/brackets.
Though standardization is still pending, all agents
have settled into a hydraulic type support to cushion
impact the placement and size of the supports still
vary.
The US support/brackets extend 3-5 inches further than
the Canadian version which hugs the body. The extra
distance is mitigated by a rubber covering around the
bracket.
All variations over the years exceed US/Canadian requirements by a good deal
and far exceed the impact
tolerance on a standard Morgan. Though not as apparent
the doors as well vary far from the Morgan standard.
They have been greatly reinforced with steel bars and
have the hinge section on the body replaced with a steel member. And lots
more...
