I found a thread asking if a 72 came with an overflow tank and the responses pretty much said it was an option on all Cutlass models until 1973. My question is, what type of tank was used on 1971 Cutlass if you got one as an option from the dealer? I see plastic and metal ones on line. A pic would be great.
Thanks

 

I can't believe no one answered by now...


Assembly Manual page 11-141 shows details of the Y72 overflow tank. It was a plastic tank that hung on a hole in the fender and a metal bracket that attached to the core support.


OPGI sells a kit with all the parts that looks just like the one in the Assembly Manual for $277.99 (ouch!).


Compare whatever you are looking at to OPGI's part number C240229.

 

I used this, it's the same size and the tank fits in the original metal bracket. The tank looks identical at a glance.
