'77 cooling system

[BillyBob]

Would like to establish 'correct cooing system' for 1977.

I've seen/read conflicting information on whether or not 1977 system used a coolant recovery system. Personally, I only have seen vehicles with a recovery system. The recovery system that I'm familiar with has a split upper radiator hose with a tube insert consisting of a rad cap (no ears for ease of removal) and a fitting for a hose to connect to the recovery bottle. The recovery bottle has a screw-on, non-pressurized plastic cap with its inlet on the bottom and the overflow on the top - pointed toward the front. The bottle is located in the RH front corner of the engine compartment.

Who can confirm the correct system?

That's the system I have on my '81.

My 50K mile all original 77 is the same.
