Source for longer TV Plunger Spring

[hemi8]

Looking for a part# or source for different size 2004r throttle valve plunger spring, I currently have a "green" spring from a Art Carr shift kit but it is too short.

I use one from Sonnax ( comes 5 to a pack ) . It's listed for a 700-4r but will work in a 200-4r . It is definitely longer .
