Actually just checked with SPF and they said they think I have a 3.46 diff ratio. Would that be the borg warner?

Your car has the Dana "GTO" diff, the ZFs start in the higher 2900s. You have a 3.46 ratio. You can install any gearset that fits the HydraTrak diff, some are available via GM and there may be some aftermarket. Do a little Googling and you wil get some info.
The "8.8" is the early Ford(T-Bird) diff used until they switched to the Dana
