I have a prop valve that i hope is for disc. There are some numbers on it. They are NC 34 KH 18 9. not sure what they mean,... i believe it came off of a 18006814 master. anybody know if it is disc or drum? thanks a lot.

flat sided machined aluminum is the later one, for rear disk or drum

Ok, I'm confused. I have a 87 GTA. I switched from drum to disc a long time ago. I heard that my master had to be changed.. SO i bought a prop and master from a 89 4 Wheel disc car, or so I was told. I just want to verify that it was the right part. Without close examination, they kind of look the same. Also, is there a way to cnage the black prop valve mounting bracket? It appears to be pressed onto the bottom of the prop. THe new one is rusty and mine is perfect. I'd like to change it. Any ideas? thanks
