Adam 61: the plastic 63-66 fan shroud won't fit your '61. But Ive got one I'll sell you never used if you want it to try to modify it. I have a '62 which had a 6cyl in it originally no shroud. When I put a 383 SBC in it, it needed a shroud. Could not find one for a '62, so I got an old '64 Impala shroud and modified it to fit. I think now that I should have just converted to an electric fan with a built in shroud and saved myself a lot of time.
