The plot thickens. Well, I'm happy that I have the overflow tank even if my model was not supposed to. I'll post up the Vin and maybe Joel can tell me the production date....maybe early 72 with some 71 leftovers? On ebay I'm seeing both steel "barrel" and plastic shrouds listed for 68-72. Maybe that is just a fitment guide vs. year correct parts. But, I also see that the fan is offset to the pass. side on the plastic shrouds.....so? I'm contemplating a plastic shroud and electric pusher fan in front of the core if it fits. I have 2 unused fans laying around the shop....would be good for cruise night. Approve

71 was the same as 72.  Plastic shroud and no external tank.

Big smile  Don't forget, that if "The General" didn't have a specific part on the line when the car came through, they put something else on it.  My '72 has "Astro-ventilation" windows in it, but the converts didn't have astro-ventilation.

What the heck do ya call that big gaping hole over the top of yer head? Shocked Now THAT'S ventilation! LOL

Convertible glass was different from the coupes, but they ALL(coupes/verts) had the "Astro Ventilation" script on them. But you are right...if the part would fit/function properly, they would substitute stuff like that. I haven't looked(been kinda busyUnhappy), but I believe the above post on the use of steel/plastic shrouds is correct.

OK, I took the time to peruse my NCRS judging manual.  So here goes:

Base with manual tranny ----Aluminum rad with an aluminum expansion tank.

Base w/AC and or automatic tranny & all L46------Copper rad and NO expansion tank.

Looks like it the car came with an aluminum radiator, then it had a metal shroud and and expansion tank.

Copper radiators came with the plastic shroud and no external expansion tank (except big blocks).

That's for 70, 71, and 72.

Only the base engine with a 4-speed and all the big blocks came with an expansion tank.

Ok so full circle....I still need to correct the overheating. I'll pop the seals onto the shroud this weekend but I doubt that would overcome my over heating issue considering she blew here top at only 74 degrees ambient. That is a new brass core rad not aluminum.
