Belt length w/ FMS A/C delete

[Rick 91GT]

93 vert, underdrive pullies, FMS A/C delete (moves P/S up), everything else is stock and there, air pump etc...

I'll measure it tomorrow but anyone know what length you have been using?

I think 84.5" is stock without A/C -- but not accounting for underdrives. You can probably get by with that or see if you can get a tighter fit by going a little shorter.
