727 accumulator spring

First time 727 DIY rebuild. 73' car tranny that's going into my 68' truck with a 440. Got the tranny tore down and found that there was no accumulator spring. Did not see a piston rod, so wth? Do I just leave out the accumulator spring? I'm putting in a TF2 shift kit in it. I read that the spring smoothes out the 1-2 shift. What should I do? Leave it out or put one in. I'm not worried about having a super hard shift from 1-2. This is a truck not a drag/street car.

Opinions Thanks
