What fan shroud will work?

[ryans69chevy]

Just curious if I'm doing this right, I searched through threads and found a couple answers, but just making sure.

I bought a 454 out of a '73 or '74 chevy scottsdale a few years back that I'm going to put into my '69. I'm using the '69 chevy radiator core support and a 4 row radiator for my '69. I'm going to use the mechanical fan with thermal clutch so my question is what fan shroud do I use? I'm also using 68-71 bbc engine stands.

Do I need a fan shroud from a 67-72 or would I need one from the 73 or 74 truck? Or would either work?

Thanks,
Ryan
