Mafia 2- Editing car questions

I was kinda bored today and started messing around with the walter utility… Came up with this so far

I just have a few questions,

-Is it possible to switch the engine with one from the hot rods?

-Can I switch the engine sounds to another car?

And these are probably not possible without changing the model, but is there any way for me to remove parts i’ve circled here?

If not i’ll just have to tuck wheels under fenders i guess
