Body Panel Replacement:
1. When replacing exterior body panels, remove rivets following procedures outlined
below.
2. Apply sealant to new panel as required.
3. Install new panel in reverse order.
Removing A Rivet:
1. When removing an existing rivet, place the drill bit on the small dot in the center
of the rivet head. Twist the drill chuck by hand to enlarge the small dot. This will
prevent the drill from slipping.
2. *Never drill completely through the rivet or you risk enlarging the hole which can
weaken the bond when re-fastened. Drill into the center of the rivet head. With drill
turned off but still in place, move it horizontally and vertically until the head of the
rivet comes off. Use an awl and a mallet to tap the rivet shank out.
3. If you accidentally drill through the material, see the following instructions.
Re-Riveting:
1. When replacing new panels, use .19 diameter rivets. The correct length rivet will
measure .25-.38 beyond the material being joined. (See diagram below)
2. When ever rivets are removed there is always some enlargement to the hole. To
ensure the strength of the new bond, follow these steps.
3. Drill the hole out to .25” diameter. If the hole is already .25” diameter then drill it
out to .28” diameter and use a .25” bolt and nut, otherwise continue to the next
step.
4. Rivet the parts using a .25” rivet. The correct length rivet will measure .25-.38 be-
yond the material being joined.
NOTE: As the vehicle ages, it is not uncommon for some rivets to loosen. This can
often be detected by a black ring (aluminum oxide) around the head of the rivet. If
this happens replace the rivet. See Re-Riveting.
