that sounds like an aftermarket tank, the factory one
is mounted on top of the upper radiator support with one
hose clamp.

The crossflow radiator uses a surge tank on top of the radiator,,,,the downflow has a bottle like next to the oil filter,,,,,

Yes Donivan65! I think I have a "downflow" radiator and I remember the tank on that side of the engine compartment but I thought it was further back closer to across from the dipstick roundabouts. Any idea exactly where that bolt hole goes?

Hmm. My 68 doesn't have a puke can(6 cyl originally, downflow), and my 69 didn't(V8, crossflow), and neither did the 70(6 cyl, crossflow).

Here's whats shown in the GM Service Manual.
This top one is a 1st. Generation
This one would me in a 2nd. Generation
But I found this at a local pick-a-part. It's a 2nd. Generation, with a wide Doghouse, but it has a radiator mount for a 1st. generation.

That would be the GS series- six cylinder. That's how my 68 is set up.

It just depends on what type of bottle you use,,,,,,find a spot,,,,,make a bracket to hold it in place,,,,we use these Nissan types for our 1st Gen Vans,,,,,

I think if they were factory, they would of come in around 1969 and 70,,,,,,
