Request advice, got a 49 merc car model for Xmas

. If I wanna make an old school hot rod,

Where do I find a model motor first gen Hemi?

Do you guys have any advice on era correct wheels or jacking up the rear? (How much? Model springs?

Do you guys ever put people in your car models?

Do you guys ever put lights into the cars?
