[Supras] Trans Mount Bolts

[Clark, Frank H.]

At the rear of the trans there is a cross brace that holds a rubber mount.
It attaches to the car with four bolts going into threaded inserts in the
chassis.
 
Does anyone know what size these four bolts are, or were supposed to be?  8mm
is too loose and 10mm is a no go.
 
The is a strong possibility that someone re-tapped these four holes to
something other then stock (3/8 ?) .  I got the car as a roller so this is a
unknown.
