'70 Cutlass radiator overflow tank and bracket
****EDIT**** Looks like I've found the pieces I need - thanks guys
After driving my car around in the summer heat - and more cruises to come - I get a spit of coolant on the garage floor when I bring the car home. I don't have an overheating problem, but I would like to find one of the dealer installed coolant overflow tanks if one is out there. I'll need the mounting bracket and any bolts that go along with it. I know there are reproductions out there, but figured I would see if there are any reasonably priced originals around. Let me know what you have! I'm not looking for perfection because it will get used - but I'll go aftermarket if I need to. Thanks!

Bob, the dealer-installed coolant overflow tanks started with 1971 models. But they will fit your car fine. Just clarifying in case that makes any difference to you.
The reproductions were done from a broken tank, so the originals look better.

Gary, yeah, I've seen some of the repros and they're ok, but I've always thought they weren't quite as good. The brackets on the originals are a little different as well. We'll see what comes up - it may take a while to find what I'm looking for.

What is your radiator coolant level COLD? If it's above the "COLD FILL" mark on the radiator tank, 9 times out of 10 that's why your car pukes coolant after a hot shutdown, and if you keep topping it off to pressure cap level it will continue to do this. The coolant will find its level.
Older (pre-72) cars without coolant recovery systems are designed to have air space in the radiator to allow hot coolant to expand. That design worked fine for years.
If it pukes with cold coolant level at the "fill cold" mark, you have a weak or incorrect rating pressure cap.
