On April 24, 2006 NHTSA published in the Federal Register a document proposing
to limit the 201U requirements to only the front seating positions of vehicles that
are altered or manufacturered in two or more stages. NHTSA also tentatively
concluded that it was appropriate to exclude a narrow group of multi-stage vehicles delivered to the final stage manufacturer without an occupant compartment because
of impracticability concerns. NHTSA also proposed to delay the effective date of
the head impact protection requirements as they apply to final stage manufacturers
and alterers until September 1, 2008.

The FR notice delays the compliance date for one year, until September 2007
while NHTSA continues to work on the April 2006 proposal. This will give NHTSA
time to fully analyze the comments and reach a decision on other aspects of the
proposal, including the proposed additional delay in the compliance date.
