I have a OBD O B16 in my 6th gen. The alternator just went out and I got a '99 Civic Si to replace it but it is too big. Will a EX alternator fit on the brackets, or should I get a GSR alternator instead? The wiring is all OBD 2, the only things that are OBD 0 are the head and block, so it cant be a OBD 0. Thanks

 

i modded my obd1 d series to fit on my ls. you should be able to make your d series work. just a little grinding and drilling on the slide hole in the bracket. i think i shimmed the bracket from the block with 3 or 4 washers.
