if the parts department do not have a photo or listing for the part it may be a seal from the bearing that was being replaced
they look like shims and many are metal in manufacture
they seal the grease in a bearing but if the bearing is failing , they will be knocked out of position and then flap around loose

Should be on the radiator side of the engine where the transmission connects. Shims are used on some models as needed.

what size motor? 4.3? V8? The starter 4.3 is located on the passengers side on the bottom side of the motor. First disconnect the battery. , Look at the new starter and locate old one. Undo the nuts on the old starter. There should be 2-3 small wires all together on one terminal. Take them off. Take the larger nut off and take power cable off. Unbolt the 2 bolts holding the starter onto the block, pull old starter out. At this point have a look to make sure that the old starter doesn't have shims inbetween the starter and block. Some starters need a shim so that it lines up to the fly wheel. You may or may not need to replace these. My rule of thumb is that if they are there , use them again. Rebolt starter the opposite of removal. When you start the engine up, if you hear a loud grinding, or a winding noise and motor doesn't turn over, then you may have to put shims in. Good luck let me know how you make out. Cheers from Nova Scotia!!

MOST GM TRUCKS USE AN ECCENTRIC SHIM FOR MORE MOVEMENT.IF STILL NOT ENOUGH...YOU HAVE A FRAME MISALIGNMENT ISSUE. HAVE A FRAME SHOP CHECK SPECS

passenger side, under exhasut pipe, against motor, close to tranni.

Nothing special about the tools but you will need to make sure you add the shim correctly

that is the only way you can adjust them

underneath the facia of the car, jack the car and look undernath the bumper cover.
