I need to replace both my door and hatch locks locks, Is there a range of Chev vehicles that are the same lock wise , or do i need to get a set form a 82 - 92 Camaro / Firebird in order for them to work

 

the locks that are used in my dads C-10 are the same as our locks, all that has to be done is swap the little arms on the back of the locks, as for the hatch, i think that may be a thirdgen specific peice, dont quote me though

 

As a parttime locksmith I know most GM vehicals from 82 up are the same lock cylinders as fbodys. S10's will be your best bet, if you not real sure just bring your lock with you to the junk yard, or just by some cylinders from a locksmith.
