Luke – maybe try rephrasing your question. If you like the looks of Magic Muffler and Mondello, perhaps ask if anyone knows the wheelbase and size of the wheels and tire diameters on those two cars. Plus rear racing wheels came in different offsets, I think back then 3 to 4 inches was common.
Once you know that information, it makes mocking up your chassis with “all” other components so they fit and work together much easier. Sometimes, just having a part (e.g. wheels) for setup answers questions, like ground clearance. I would guess in 95% of the components, form follows function. When you have completely mocked up your topolino for the umpteenth time with “all” your parts, you might just surprise yourself that it resembles the look you are after. Alan
