Door lock and parts!

Bought a 1994 hardbody today! Brilliant thing, very well taken care of. I’m not planning on making it a project truck, I’m just planning on running it till it dies.
Issue is, I bought it without a driver door handle, so you can only access it by leaving the window unrolled and opening it from the inside. Not worried about it being stolen, nobody knows how to drive it. Mostly just want to get it fixed before winter.
Any idea how to replace the door handle/lock?
Any and all advice welcome!
