can I use a alternator from a 7M on my 5MGE?
Thanks, Mikael.

You might have to change the pulley on it but yes it has been done before...

As always, search is our friend. Most things have been covered here a couple of times.

Also depends on what year of Supra/Cressy.

82 and 83 models have a different voltage regulator and require a diode to be bridged somewhere, if I recall correctly. It should be contained in the write-up.

Yes, you can use a 7M alternator on your 5MGE. You will need a different alternator belt if you keep the 7M alternator pulley though. (The 5M pulley is 2 ribs wider I believe)
