tri pod front ???

[FED 387]

Have an older dragster with a straight front axle want to put a tri pod front or narrow the axle down to get a little more contemporary look to it-- problem is the frame comes to a point not raised or boxed like the newer cars are---any one got any ideas how to do this or has anyone done this---do not want to get into a major project or lot of expense here---Thanx fed
