When I did my 1987 Bill Venturini car, most of the contigs were taken from google images and resized manually, sometimes with editing to make them more accurate.
With these lower series cars, you will be hard pressed to find contig sets for them, so you will likely have to do most of the legwork yourself (and the lack of photo refrences and hard to find logos is why not many people do the lower series cars but the most dedicated)
Sometimes you can find old decals on ebay that can be cropped out, or used to mock up a logo, as well as identify sponsors that might be more obscure.
