Gee I have though of asking you questions due to your avatar, but alas I only have a Brookville FRAME! I am getting ready for a BeBop fiberglass body to save a few bucks, so I can't tell you about the bolts for the steel body. There is a '29 Sport coupe on display here in Ashland (with the label "Spirit of Ashland") at a Chevron station and I have been swung over to consider saddle tanks so I can get a rumble seat. The stock rumble seat is really small, and made more so with the cardboard panels along the side. Sorry I can't help, what did you decide about the gas tank using a trunk lid, verticle or flat?
