DC2R injectors all OBD2? Do ob1 clips work?

[DLO01]

I want to get some injector clips for my DC2R injectors..
are all DC2R injectors obd2? Do obd1 clips work for them or only obd2 clips

DC2R's are obd2. 98+ I think?

obd1 clips will work by shaving off some plastic on the injector plug connector.

I would however be more inclined in doing it the proper way and get obd2 clips.
