Front end wobble.

Check with the people in your local hot rod scene. I'm pretty sure the is someone in your area that is competent with diagnostics & alignment. It took me almost a year to finally find someone to align my bracket car to the specs that "I" wanted. Most of the places were hit & miss & once or twice the car was just plain dangerous to try to drive, much less make a mid 10 second pass with it. Keep searching, there is a good shop out there.
