What bushing material are you using?
Whose sway bar?
How tight are the end link bushings. They should be tight.
Are they all in square, not deformed?
btw I had to unweld the skid plate to get the sway bar in. FF 1-1/8 is plenty of bar.

Wait to make any more changes unit the welded K frame is installed-be sure you gusseted the heck out of the steering box mount. The k frame will change your handling. Your torsion bar size needs to be at least 1.00 inches. Your tire choice and size affects handling too. There are no simple answers.

Remember the goal is to achieve a balance so the car rotates thru a turn and doe not rattle your teeth when driven as transportation
