Insert the plastic spacer [M] and plastic spacer with notch [N] into the tubes on the lower truck brackets.

The spacer with the notch goes in the tube with the notch. Align the spacer notch with the notch

in the tube

For some model years of Chevy

trucks, it may be necessary

to use an additional spacer on this side.
