javden,
You may check the Northwest Vintage Speedsters web site at
http://www.nwvs.org/ and you can see different speedsters listed there, with very different looks.
Also, you can check my profile where there are pictures of two speedsters the Blue on is fabricated with International Hoods for the boattail, and the Ivory Speedster Boatrail if made from a 47 Chevy hood.
I don't know of any Speedster kits, but I think Mac's Ford Parts has a kit they sell.
