Question car died, think alternator, please help.

hey everyone I need help and sadly this is my first post,
ive just had my first breakdown and I'm stumped as to why its happened....

so today I left the side lights on for a couple of hours by accident, the car didn't start as usual and struggled like it would from a low battery which was to be expected. so I waited a good 5 mins letting it idle then dropped my girlfriend off a good 15 drive away, on the trip the battery light stayed on and when stopped at traffic lights using the indicators it felt like it was going to stall. but after about 20 mins of driving the light went out and it felt good again.

once home I turned the car off and tried it again to see, and it didn't start.... it did bring on the dash lights and prim the fuel pump but couldn't turn the motor over. so got a jump start and it fired up instantly.

i tested the battery and it was 11v, let it run for a wile and tested it running to check the charge and it was dropping now to 10v. obviously that points to a stuffed alternator.

am i right?

other question is what alternator would i need? the cars a 1974 280SE.

huge thanks for any info.
