fd alternator on fc s4

fd alternator on fc s4
so , for the longest while i was running an s5 alternator on my s4 . i upgraded to an s6 (fd) alternator, which does have the same clip on it. so it was plug and play.
issue is. the fd alternator sits way to far forward. and it needs spacers to fill the gap between the mount point.
i have been having issues lining up the pully, so the pully is inline with the others. i have been having issues, i threw out the bearings on my alternator, i believe the bearings went out because of the alignment with the other pullies.
i have already replaced the bearings, i am installing this alternator and i just dont feel right about this alignment.
please tell me how you fit your fd alternator on your s4 fc. hasto be an s4 engine, the s5 has a slightly different mount (requiring spacers on an s4 to fill the gap on the main mount)

You know, all I did was mount my S6 alternator in my S4 using the stock S4 Alternator spacer and I've not had a bearing problem ever. And I've been running an S6 alternator in it for about 4 years.
Interestingly, I have been having occasional bearing problems with the S6 alternator in my S5. There shouldn't be an alignment problem all considered, but from this observation I'll take a closer look. I've been running lifetime warranty O'Reilly rebuilds in the S5. But so easy to swap out, and nothing out of my wallet each time, never worried about it.

this alternator sits about 1/2 inch back to far and the belt leans back. idk if its caused my bearing issue or not..... but i am having issues. i did have to have bearings replaced once so far.

im just trying to get a feel for what other people have done to get an fd alternator to work on their fc.

Rather than screw with the alternator bracket location...
Look at where the pulley is on the alternator.Too close to the casing.Get a bushing(spacer) put in between the pulley and the alt and then that would bring the pulley out far enough to line up the belts.
My Fd alt fit fine and lines up perfect also.

i think the issue is the alternator.
first it sat too far forward, then it sat 1/2" too far back. which is it? the alternator pulley dimension placement is the same as the S4 and S5 alternators. place the S4 spacer at the rear leg of the alternator and call it a day because that is how it is supposed to sit. if it's eating bearings then perhaps you are tensioning the belt too tight.
