yo;
You can remove bed side & B pillar trim panels; there is a "captive nut plate" inside the B Pillar; so when unscrewing the bolt w/ a Torx T-50 bit that capt. nut plate won't fall to da pillar bottom
Get another from a yard or ask a local auto body (or supply/paint) shop
Watch out for the Dorman HELP brand stuff now....the driver/passenger door striker kit w/ bushings, 38445 are not fffin good..bushing diameter is way off and striker frame is off as well....it will bolt-in, but aligning it for a no-rattle fit is efffin a waste of time and possible damage to passenger or driver. the Dorman HELP tail gate striker bushings pn 38424 are a good fit & the door bushings driver/passenger bushings are incl. in this kit & fit better than the 38445 part!
