1967 A Body V8 Fan Shroud and/or suggestions

Doing a 340 conversion on a '67 Barracuda. Original 273 V8 car, heat only, auto trans. The a-bodies experts here have done a lot of posting on this topic, and I've done some homework. I know the part I need is extremely hard to find. I'm looking to make sure I'm going after the right part so I can pay big money with confidence in the fit, and possibly locate the part itself.

I believe I need a part number 2785312 fan shroud.

My radiator is a 2785929, which forum members have said goes with the "312" shroud. The links to the Mopar radiator guide specs say I have a 67 A-body / 22" / 383 / Heat / Either Trans radiator. I expected the 273 car to have a 2785973 radiator as the guide says it would, but what I have may not be original. If I'm reading it correctly, the "312" shroud fits both of these 22" radiators -- and only those, unique to 1967. The reproduction shroud cited for '68/'69 340 applications seems to be for part number 2785614 -- not for the 1967 V8 fan shroud, the "312".

Options in order of preference - please weigh in with corrections or better ideas!

1. Locate a "312" as the match for the 28785929 radiator. Pay high but fair price :)

2. Replace radiator with a '68 or '69 part, use the reproduction shroud or original (also unobtainium).

3. Go with an aftermarket radiator / shroud combo. I started to look at this but the models available don't map to '67 applications. I am wondering if this is a custom order or maybe a bracketed thing that can be made to fit.

4. ??? Other ideas

Thanks !
