Go with the Jack Dainels, it fits the muscle car look IMO.

 

I don't have a good pic of mine but you can buy nice stainless or aluminum overflow canisters on e-bay.

 

I do like that plastic one Fakesnakes.. You should be able to see the fluid I think.

 

The older cars didn't have recovery tanks because they weren't ment to run
under pressure like the modern cooling systems. It was standard practice
to not fill the radiator all the way. The fluid level should be about 2-3" below the fill neck to allow room in the radiator for expansion. Mine is filled to this level and never leaks and doesn't overheat (and there's no recovery tank).

 

I filled Mine up all the way when I put the new engine in and it leaked coolant out the overflow hose until it was at a low enough level where it had room to expand. It kinda just settled itself out and i haven't added any coolant and it has never overheated on me. (also has no overflow tank)...

 

When you change a system without a recovery tank to a system WITH a recovery tank you need to make sure that you use the correct cap. The one for a recovery system has a little one way valve on the inside. It is about the size of a half dollar and has a spring. You can lift it up with your fingernail.

This one way valve allows coolant to be drawn back from the recovery bottle as the system cools. If you don't have this type cap, your recovery system is only keeping the expelled coolant from reaching the ground but never allows it back into the cooling system.

 

Don’t install a 16 or 18 lb. cap. Ideally you want 13. A higher pressure rated cap will cause higher pressures in your engine from the expanding water. This can cause a seal or hose to blow out of an older “tired” motor.

Look at my photos in my photo gallery for a nice stainless steel over flow. I added mine because my car is my daily driver and it gets real hot here in North Carolina sitting at red lights and what not.
