rick, my dato ('71) has dual reservoirs - well did have before I pulled them
out. As far as I know, the second was a safety unit, so where the first
fails, the second can pull the car to a halt safely, but I'm not saying that
they are for the front and back seperately, just saying what I heard. It is
also written in the gregories manual like that. The 180B booster has no
warning light leads coming off it as I know it (3/4"), where the 240K (7/8")
has the leads for the light. Maybe the model of 180B I have it different to
the majority, or maybe the wires were already taken out when I got them - I
don't know. Both 180B and 240K's have dual reserviors though.
