Been given two alternators one 14V 23/65A & the other is a 14V 40-70A

Today i took the one off the BM & its a 90A, question is can i use either the 65A or the 70A as a replacement? or are they not good enough?

I've only been told the ones i got.. 65A-70A fit 91 to 98

 

if you've got a 90amp alternator you'll need a 90 amp to replace it really

there's going to be a bigger load and the tiny one won't be able to keep upwith demand
