Need a radiator solution for a 69 dart

I was able to come up with a 68 gts radiator and shroud. I have it in and it bolted right up.
There is a 7 blade fan that came with it, but no clutch. Just a spacer.

It sits right as far as being halfway in and halfway out of the shroud. It doesn’t have a part number that I can see.

But is that fan too small for that shroud. It’s about 1” down
The shroud is 20” across

I want to put a clutch in there. Maybe I need the 215?

Also……what is the clip that secures the shroud together on the bottom.
