68 R/T Charger trans kick down

Looking for a return spring that goes on the transmission kick down linkage. This is going on a 68 R/T Charger 440 numbers car. I have a parts manual for 67 and 69 but no 68. They call for two different possible springs. One White and the other green. Both with different number of coils as well. If you have an original one, I'd be interested in purchasing or at least seeing a pic of it installed.

Thanks in advance

The 68 parts book lists 3

2536453 - 19 coils - black
2806464 - 75 coils - yellow with red stripe
2946611 - 38 coils - red with blue stripe

I think it's 2806464 - 75 coils - yellow with red stripe by the parts book

Thank you! Do you have any idea if these are being reproduced?
