Are all A Body door latches the same for all years?

1967,68,69 and 70 should be the same, they are on a dart because doors all work,by changing glass. or lock button is back futhur.

I don't think so - they physically will fit and look the same BUT the lock linkage and arm are different.

I had a damaged one on my 69A and bought one out of a 68A not knowing the lock button location was changed farther back on the door on 69 and later cars.

I ended up getting one out of a 71A.
