Building a vehicle ingame?

Hi Ladies and Gents

Does anyone know of a tutorial that covers in-game building of vehicles, Like picking up a wheel and going through the hardships of having to attach it to the chassis,
before you can drive the wreckage you have to revive it by jacking that body up and adding the wheel, but there is a plot twist you have to tighten it with 5 nuts first (Depending on the vehicle)

If there is no tutorial is there some savior out there that can help me with this piece of the grand puzzle?

Drama aside, I’m planing on making a rather detailed game but i am stuck at this piece of it would really appreciate assistance on the matter
