There are a couple websites that might lead you to some info. I don't have the URLs, but you can Google them. One is the Binder Bulletin and the other is called Old IHC something-or-other. Someone did have books available, but they were $50 each - more than I wanted to spend just for an assembly drawing of my '35 steering box. I know this isn't a lot of help - but with a bit of "cyber-chasing", I'm pretty sure you can find what your looking for.
The other website is oldihc.org tons of info and links to vendors for about all you'll ever need. I love ol'cornbinders got any pics? Pool
