ran into an issue with my doors. apparently the door striker is different from 51 to 53.... has anyone else installed a later model door on a early body? my body is a 51 but the doors are 53. right now the latch is only latching half way. looked at teh lmc truck catelog and noticed there is a difference in the strikers. will the 53 model stricker bolt up the the 51 body? need help on this badly so i can continue moving forward.
