The first pass , shows the car can work with what you have . Just need to control the front

What shocks are in the front ?
What leaf springs in the rear ?
What’s the weight front and rear?
How much front travel?

Looks like your rear worked well on the first pass , but the front was too loose or the front is too light . A lot of front travel with a good front shock will give you a lot of control . Also 10-20lbs up front can make a big
Difference . Or just moving some from back to front
