1970 L/78 Nova brake valve setup question

[nuch_ss396]

Hi all !

I have a fast question I'm sure someone can answer rather
quickly. A friend is restoring an 02-C-1970 L/78 Nova and
we ran into a problem with the brakes. Disc brake Nova's
used two different junction blocks, brake valves, and
pressure regulator valve setups depending on the build date.

We believe there were two different setups used ( early vs.
late ). It appears that the early build used the same setup
as that used on the 69 Camaro.

Can anyone tell me what the cutoff date was for one setup
vs the other? Also, if we need the later setup, can
someone post an image of the complete assembly at the
master cylinder location so we can see the routing of the
lines, etc.?

Thanks,
Steve
