You must be talking about the fan shroud, not a shield. They were produced in two halves and spot welded together.

Perhaps this photo will help.


At the top, you can see where the overlapping halves are spot welded together. This was early in my restoration, and I had just painted the shroud so it stands out nicely. Ignore the engine, it is non-original at this point.

Also the top flat section should have a letter stamped. My 64 with date stamps in April has letter D stamped on the shroud.

Doug, good point. I'm doing a 63 and mine also has the letter D. Would have never noticed were it not for your post. Mine was also difficult to discern as it was partially on the roll in the stamping instead of being entirely on a flat surface. Must have been Friday afternoon or Monday morning... Don

Dave, like your fan/clutch upgrade - or was that part of the AC package? I have a 63 and am adding a seven blade fan and clutch from a 93 Caprice 9C1. In the process I learned that there are at least three different circumferences in the bolt patterns and the 9C3's was greater than either of the two patterns in the original water pump flange. Probably could have elongated them myself but this was no place to screw up and I paid a machinist to do it.

With the fan & clutch installed can you then install the radiator/shield or must the radiator/shield be installed first?

Thanks,

Don

PS Is this the car with the 327/300 engine?

That is stock fan blade and stock replacement clutch (Hayden, I think). My car was originally a 283 with AC, so it had the shroud and the 5 blade fan with clutch. The same is true for the 327 with AC (different radiator, though).

I did an experiment with the Heavy Duty variant of the Hayden clutch by modifying a fan blade's mounting holes to fit it. It did move more air, but was incredibly noisy and I think it even hurt performance. So that experiment did not work out well.
HD vs standard clutches (HD on the right)

You can see the original bolt holes on the fan blade, new holes bolted to the clutch.


The shroud must be installed first, then the clutch/fan assembly can be installed.

And yes, this is my 64 that has the 327/300 (bored/stroked to 383) in it now. The picture above is with the old 350 based 383 I had in it from the late 80's.

I suggest another better way to install the fan and clutch.

Install the fan and clutch without the radiator and fan shroud in place(much easier than having the fan shroud in the way during installation of the fan and clutch.).
Hang the fan shroud over the fan (with a large towel) then install the radiator and fan shroud at the same time(probably need 4 hands to hold the radiator and fan shroud during installation).
I have done it this way at least 5 times...

I agree with Paul's method. But to do it with just 2 hands, make some 5/16-18 studs and screw them into the lower holes in the radiator support. Hang the radiator on them, then hold the top of the radiator with one hand and lift the shroud in place with the other hand. Then start the bolts.
