Does anyone know how to adjust the idle on my carb? (83 22r stock carb) I was playing a bit today and I couldn't find the adjuster, shouldn't it just be a screw? Few other questions, Will I have to lengthen my rear driveshaft with the chevy springs? Where do I mount the hangers for the shackles and front hanger for the chevy springs? Do I use chevy shackles that are on the truck they come off? I can't afford a welder decent enough to do the hangers right now, how much would I expect to pay a shop to weld on the hangers for the springs? thanks guys
