Have you thought about changing the driveshaft?
It sounds like something is out of balance,and the driveshaft is making the Diff blow seals or bearings.
check the whole Back end while you are at it,.There is Stuff(like the camber link) that is not really visible by just looking under the car,You need to jack it up and inspect it,hands on.

have hade the drive shaft done, broke that and has been upgraded so is now strong enough for the transmission, have had the transmission shaft upgraded to a 2 piece billet shaft so transmiision is now strong enough for the engine, now the only weakness is the diff and front diff mounts, what can i do

I don't even know how you are breaking diff mounts on an 87 NA automatic. Something must be very wrong. When the front diff mount fails, what happens? What is the condition of the rear diff mounts?

In what condition are the engine and transmission mounts?

i have had the engine rebuilt, ports have been opened up as far as a 6 port can go, transmission is rebuilt to new with stage 3 shift kit & 2 piece billet shaft, drive shaft has been custom built , this car has some power am getting 100MPH / 166KPH FROM 2nd gear @ 8000rpm & breaks traction changing into 3rd but am blowing diff centers & breaking front diff mounts
