LS2 Alternator Rear Bracket Interchangeability?

LS2 Alternator Rear Bracket Interchangeability?
The LS2 GTO shares the same accesory offset as the LS1 F-body. Posts like this one list the F-Body alternator brackets for use with the GTO LS2, seemingly because the F-Body brackets are less expensive.
The LS2 GTO rear alternator bracket (92059707) appears to be much longer than the F-Body rear bracket (12556915). Are the rear brackets interchangeable if using the stock GTO alternator?
My drivers side motor mount can't slide fully forward due to interference with the GTO rear alternator bracket.
TIA.

My E36 Jags That Run kit also uses a slider mount. The stock GTO rear alternator bracket interferes with the mount just a bit. Next time I'm in FL, I should be swinging the engine in for its first test fit. If the rear bracket proves to be an issue, I'll look for an alternative or consider eliminating it altogether.
I just found a picture I took before removing the stock accessories. Compared to the picture above, it looks like the F-Body rear bracket bolts to the hole with the green arrow? Assuming the GTO alternator is dimensionally the same as the F-Body alternator (I don't know if they are) it would appear that using the F-Body rear bracket would eliminate interference with a slider motor mount.

Yes that's what my set -up looks like. The only difference is the alternator housing where the rear bracket bolt attaches. See how your GTO alternator has a solid round extension where the F-body has the square, 2 piece look to it? My only concern is the length there, too short you can run an aluminum spacer, too long and chop city time.
