If your striker bolt is good and the plastic/rubber sleeve is in tact… how is the sheet metal that holds the striker bolt … my 93 (due to offroadin) had a problem with the sheet metal and I had to add to that to stiffen it up to hold the striker bolt more firmly thus holding the door more firmly thus stopping the squeaking. The only thing that holds the 60 door in place is that striker bolt... well the 2 hinges and the striker bolt.
