5.0 Front Servo Spring

So found some information. Front Servos were made larger in diameter starting in 1971 904 transmissions. I have a 68 727, I wonder if the front servo is the same size as the front servo in my 904.

I wonder if that's why it has a slightly larger 2nd spring in the front servo. Maybe it was just added when the trans was rebuilt and the VB was modified.
