Mike -
I had such a problem years ago with this particular
year car - getting one to fit. I bought a new one at Cadillac, they'd
had such a device early on. It fits nicely behind the front yoke, between the AC
discharge line and the the inside of the right front fender well. It is generous
in size and worked for me for many years. I also bought the cap with the two
valves in it. By the way, there's a lot of talk now on our site about the amount
of water and antifreeze to have in the system. Those who recommend no more than
fifty percent are correct. What isn't being said is that the molecules of
ethylene glycol are much smaller than molecules of water; the glycol molecules
actually fit in between those of water, hence a 50/50 concentration is fine, and
to go more "rich" with the glycol. the freezing point actually rises. If you
should add a gallon of water and a gallon of glycol, you would have less than
two gallons of solution......Bob Harris
