1972 Plymouth Duster Alignment failure

you are on track. the K is the foundation. correct pan and pickup, new mounts. maybe get new front end shop!?????
I feel fore you. I am now working behind someone that started a project, quit it, sold it, next guy sells off parts, i'm comin behind and putting it back together and lookin for ALL the little parts and pieces ! LOL
I know how all this gets into your pocket, BUT once you get it right and can drive down the road as it should, LIFE will be GREAT!!!!!! persevere!!!!
