If not already installed, you can get a specific version of a component by specifying the toolchain when calling rustup (like +stable, +1.44, etc). In your case:
rustup +nightly-2020-03-24 component add rust-src
The source can then be found in ~/.rustup/toolchains/nightly-2020-03-24-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/.
