It may take a few things, but start simple IMO.
On my car limiting the front end travel helps a lot. More rebound damping in the front shocks helps also. I replaced the stock A-body front end bumpers that were about 1.2" tall with ones about 2" tall. These were aftermarket (Lakewood?) bumpers for slapper bars that I cut down since they were way over 2" to start with. I use shims (large flat washers) between the bumper and the frame to fine adjust travel (.125" each for starters)
