11" brake self adjuster spring

All-

I have all the 11" brake hardware that I need, except the self adjuster spring. I've bought 2 different kits (Cordoba, D100) and the spring that was in them is about 1-1/4" too short. Rather than roll the dice and be wrong again, I thought I'd ask you all if anyone knows the required spring? Pic below. Thanks!
