Do not forget to replace this little rubber seal that stops water getting into the boot lid via the handle hole. For sliding window type cars the door locks use ADA3817.
On mk3 models the small door gasket on the Mk3 wind up window door handle is
CZH1729 and the larger one is
ALA5795 and on the MK1/2 doors the small gasket is
BMP135 and the large is
ALA7844.
this is to suit the later mk3 on lock
for the lock used on mk1/2 and van/esate use the smaller ADA3817 seal
