Alternator belt

I have a 1980 MGB with no A/C and need to replace the two belts. Obviously it needs an alternator belt, but the other one seems to be attached to what I am guessing to be a smog/emission pump of some sort?
Neither attach to the fan as they are electronic from what I can tell.
So does anyone know the stock/OEM numbers for the two belts. There is no local dealer I could find to ask, and places like Autozone, Napa, etc. say they need the number to cross reference them. Of course if any of you have the name/numbers of aftermarket belts that would fit my car, that would be great also.

If the one belt is only for the smog pump(assuming that is what it is), is it really needed, or should I just take it off? We have no emission testing in Florida.

Lastly, I have changed many a belt on different cars over the years, but is there anything special I will need to do to change these?
 
If you are using a local parts house, why not just take the belts with you?
They don't need a number, just the belts.

Any good parts place will have 7mm (I think) v-belts in a variety of lengths.
Let them measure the width and length and you're all set.

I would not remove the smog pump belt without a proper de-smog. That entails a little bit of work - removing some equipment, rerouting some hoses and plugging the air injection ports in the head.

If you do a search, I am certain this has been covered in detail.

I might be mistaken, but it looks as if mine has been altered with at least one hose closed off. I have no idea if it has any effect on it's performance. I'd just as soon disconnect the whole contraption as it must rob this small engine of power.
