Start selectively removing a spring leaf or two, trial and error, to see if it'll get down in the weeds like you want. Ain't much more that can be done except to replace the front crossmember with one being MORE flat, or having less of a U-shape. You really don't want to do something dumb like using longer shackles, which of course is almost impossible on a '34 anyway with the spring right over the axle. DD
