Swapping Hands on a Tudor 76100

[stxfan10]

I saw the below Tudor Submariner model 76100 from the 70s on EBay.

The seller is offering the original hands and bezel as part of the sale since they were replaced at some point.
How difficult and or expensive would it be to have those items placed back on the watch?
I like the somewhat beat up look.
The dial doesn't appear to have been refinished or resumed.

Thanks
