29969 is stamped on the master cylinder. And from what I have been reading it appears to be for a 4 wheel disk corvette.

The booster is a dual 8"

The car did have rear drums when I got it.

I changed the rears to disks, flushed the lines.....but never changed a residual valve.. ( I have been reading about this)

The car will not lock up the front or the rears, and the pads do not seem to drag... the car rolls forward easily if I throw it in neutral....and my driveway hardly has a pitch at all.

It does say that I need 18" of vacuum for this kit....My car idles at 11" in gear.....but If I drive down the road I can get 17" While I'm driving with that much vacuum.....if I try to lock em up it will not. The pedal does not seem like it is assisted that much by the booster...Maybe my booster is shot....The car did sit for 13 years before I got it.....the mechanical fuel pump was shot..
