Check out my vintage overflow tank!! Super Rare!!!

I used a jaz 1 quart return type bottle mounted in front of the core support on the passenger side. If I ever figure out how to post a pic I might do that so you can see what I did. I found that with the use of a heavy piece of strap I could use existing holes in the core support and bolt the thing together with some washers used as spacers - came out pretty neat. Only issue with the jaz bottles is that they dont have a level indicator - no problem - I used a piece of clear hose going to the bottle so you can see where the level is inside the bottle - sort of like a u shaped balance tube if you will.
