my son is having issues with handling after lowering the suspension on his 49 3100. He wanted the lowered look so we installed a dropped front axle and removed some leaves from the springs on front and rear. Installed modern style shocks, front sway bar and power steering conversion with a 70's integral steering box. The truck now seems too light and bouncy in the front end. Would air bags or air shocks help or any other solutions? Dave V
