How to get rid of understeer in a 1970 340

Recommendations:

1. Stiffer front T-bars ~1.0" or greater.
2. Stiffer front anti-roll bar. A 1 1/8" bar is available.
3. Rear anti-roll bar. Even those that mount on the axle are better than nothing.
4. Same size wheel and tire F/R. Larger rear tires promote understeer.
5. Fresh F/R suspension bushings. Polygraphite preferred but even new rubber bushings better than old ragged worn out stuff.
