Help with this spring

[red 69 runner]

Changing the single pot master cylinder to a dual pot in the 66 Belvedere and I am planning on using the original push rod but the return spring was broken in 2 places.Anybody know where I can get a new one?

??? My original 2 pot master cylinder (70) doesn't have one of those springs.

Also, I suggest you be SURE the pushrod length is correct or you may have some brakes that don't work....you may be OK, I just don't know for sure and I do know that those rods can be a problem with brake swaps.
