reinforcement
and remove tape as shown in figure 9.
NOTE
Upon completion of all drilling, remove any sharp edges and burrs.
(5) Using marked locations on reinforcement, drill 0.406-inch diameter clearance holes for rivet
heads as shown in figure 9.
(6) Locate, mark, and drill seven 0.125-inch diameter holes in reinforcement as shown in figure 10.
(7) Aline centerline on reinforcement to centerline on left side body and "B" pillar. Using reinforcement as a
template, drill seven 0.191-inch diameter holes through reinforcement and in left side body as shown in figure 11.
(8) Apply 00206 part 1 activator to left side body and "B" pillar as shown in figure 12.
(9) Apply 00206 part 2 adhesive to mating surface of reinforcement as shown in figure 13.
(10) Install reinforcement to left side body and "B" pillar and secure with seven M7885/2-6-3 rivets as

d. RIGHT RABBET REINFORCEMENT INSTALLATION.
NOTE
It may be necessary to replace weight and dimensional data plate if
damaged during removal.
(1) Mark an outline around weight and dimensional data plate on right rabbet assembly as shown in
figure 14.
(2) Remove weight and dimensional data plate from right rabbet assembly as shown in figure 14.
(3) Remove four screws, washers, and bracket from right side body and "B" pillar as shown in figure 2.

• Upon completion of drilling, remove any sharp edges and burrs.
(4) Position 12342380 reinforcement to inside of right rabbet assembly and position 12342730
template to outside of right rabbet assembly. Using template, drill eleven 0.191-inch diameter holes
through right rabbet assembly and reinforcement as shown in figure 15.
(5) Use 0.328-inch diameter drill bit to countersink marked holes on right rabbet assembly within
