68-72 drag truck rollbar

[blender]

I have a 9 sec 68 and I am going through it and redoing it to go faster, I am looking for any pics or info on rollbars I am wanting to add a 11 point roll cage but not go out the back window to to tie into the rear frame I want to do a full cage all the way to the front frame under the hood 9 points in the cab and 2 points to the front frame does anyone know if this is passable or does anyone have any other suggestion that wont go through the back glass.

Thanks,
Blender
