I think I still have Lebaron-Bonney's '30-31 Roadster interior and top installation instructions lying around somewhere. Send me a private message via this website with your direct email address and I'll scan the sheets and forward them to you if I can find them. Copyright issues may prevent me from simply posting them on the general discussion page, whether LB is still in business or not. I don't mess with copyrighted material on a public forum.
I won't be able to do this until tomorrow morning, however. If someone else can help you in the meantime, great!
