RE: GP Waco?
I've got the DL-30 rear carb in mine. Took a bit of tweeking to get the throttle linkage set-up. Had to do a "Z" bend to allow it to line up with the throttle arm and still go throught the fire wall without interferring with the fuel tank. Also had to cut a slot in the battery tray for clearance of the linkage. Added 2, 1/8" lite ply runners on each side of the battery tray to keep the battery above the throttle linkage. For the other stuff, most of it has or will explained throughout this thread. Also look at post 515 for what I did on fuel lines.
