The #1 mount on heavy trucks has a formed scuff plate
added in the lower cushion. A shorter body bracket
moves the mounting holes inboard and provides the same
mounting location as present light trucks for the purpose

shorter cab.
Body mounting-cab rear is shown in Figure 3.
The #2 mount on the 10-Series truck incorporates an
isolation collar to reduce noise transmitted into the cab.
A "Dairy queen" type mount replaces the shear type
recently used on 20-30 series, and the M60 series.
