Alternators physically different?

I got a complete OBD2b GSR that came from a 99-00 civic SI.

I am putting it in a 92-95 and converting it into a OBD1.

Are the only things I need to convert are the alternator and distributor?

Also are the distributors between OBD2b and a OBD1 physically different, because when I try to put the OBD2b alternator on the OBD1 GSR brackets it is off by like 1/8 inch. So if I actually get the OBD1 will it fit or are the brackets the culprit?

Thanks in advance

The alternator plugs between OBDI and OBDII are different. I believe the OBDI has a square plug and OBDII has a round plug, Or is it the other way around? I forget, but they are definitely different

So if you are using the Civic harness you'll have to swap out the plugs. If you use the motor's harness then you'll be ok.

I knew the plugs were different, but I meant the physically housing of the alternators or the brackets. Are they different between OBD or car?
Thanks

Hypothetically if they physically fit in the bracket I have I can use an OBD2b alternator on an obd1 engine if I swap the plugs? If so swap the plugs on the harness to fit or on the alternator?

Thanks
