Welcome to the best website on the web for help with your Streetbeasts. My build is presently on page two and has lots of descriptive photos. My build thread is titled "Street Beasts '34 build starts".
Separately, I highly recommend contacting people on eBay who are selling their incomplete Streetbeasts builds and asking them to sell you parts off of their kits. That's how I was able to buy a replacement shell for my 34 roadster from Streetbeasts. The other route is to either fabricate your own parts via a welder or purchase them from catalogs.
Best of luck with your pursuit, if you have any questions there are lots of people on here that are willing to help you out.
