26. Carefully inspect the notched area at the center of the rear of the P.S.I.R. reinforcement. See figure 9.
27. If the reinforcement design matches the original design in figure 9, a new I/P pad must be installed.
28. If the reinforcement design matches the new design in figure 9, install edge protector P/N 22659572 as shown in figure 9. Make sure that the edge protector is centered and fully seated onto the edge of the reinforcement.
IMPORTANT:
THE EDGE PROTECTOR MUST BE CENTERED (SIDE-TO-SIDE) ON THE REINFORCEMENT AND MUST BE FULLY SEATED ALONG ITS ENTIRE LENGTH.
29. For Buick Skylark models requiring installation of new I/P pads, refer to the following procedure for installation of the applique to the RH side of the I/P pad just above the I/P compartment (glove box).
a) Carefully inspect the location of the applique on the I/P pad being replaced. Pay close attention to the back side of the pad and note that there are two holes in the sheet metal reinforcement that line up with the posts on the applique.
b) On the new I/P pad, locate the corresponding holes in the sheet metal reinforcement on the back side of the new pad. Use these holes as guides for piercing two small locating holes in the I/P pad skin.
c) From the back side of the new I/P pad, use a scratch awl or other sharp instrument to carefully pierce two small (as small as possible) locating holes through the outer skin of the I/P pad.
d) Thoroughly clean the area around the two piercing in the I/P skin to assure proper adhesion of the new applique.
e) Position the applique to the I/P pad and push the pointed posts part way into the pad through the previously pierced locating holes.
f) Peel the backing from the applique adhesive, align the applique as required, and fully seat the applique to the pad. Apply pressure evenly to assure complete adhesion.
