Having 2-3 shift overlap - Thinking of switching from 4.2 apply lever to 3.8 - Any Other Thoughts?

Is there a center spring that I could order or pick up to add to my current billet servo? I hate to buy a whole new kit if I could avoid it. Maybe someone has an extra? Maybe I'll talk to the locan transmission guy. Just asking. I want to get it back together asap.
Thanks again, guys.

A stock one will work fine if your local guy has one.

You can’t buy just the inner spring to my knowledge because the rod diameter is smaller on the dual spring compared to the single spring.
