Better Alternative Alternator for 240K

I've seen datsun 1200 A12 engine and they are using Falcon alternator rated 70-85amps (two version) but you need just a few washers

and I had a look at Bosch's catalogue and Sunny B310 (similar engine with 1200 A12) have the same alternator with the 240Ks

so that means we can use the falcon alternator as well?....
