Time to ask the people in the know i hope..

I have a nice clean unmolested rochester carb sitting on the shelf in my hut that came with my k5's engine and i'm having nothing but trouble finding a rebuild kit for it.
I have the only numbers that i can find on the carb on a round disc which is pressed into an indent in the side of the bowl directly behind the primary throttle arm.
As it reads on the disc...7026261k5
Could anyone point me in the right direction for a rebuild kit for the above number.
Thanks...
