Please check the Thumb lock position to your old Handle
How to check:
Look on the back of the inside Interior handle where the thumb latch passes through. There are 2 slots 1 marked "A" and 1 marked "B".
If "B" (Lower Latch slot) is where your Thumb latch passes through you have a Offset Latch
If "A" (Upper Latch Slot) is where your Thumb lock goes through? You have a Center Latch
