LGB base insulation part numbers have changed. The
front and back insulation set, Item 9, is replaced with
the following part numbers.
Note: Both a front and a rear insulation piece must be
ordered now, instead of a set.
On the larger bases, 2 pieces make up the front insula-
tion and 2 pieces make up the rear insulation.
D Base =
A front and rear plus an E front and rear
E Base = B front and rear plus an E front and rear
F Base = A front and rear plus a D front and rear
G Base = B front and rear plus a D front and rear
