disc conversion then alignment no good
I did the same conversion you did. When I got done my tie rods where all out of wack. Did the old Nascar String trick to get it to the shop. An Old Timer Shop, still uses mirrors and the projector. Old man says since I have power steering +2 degrees, I forget caster or camber.....
Car rides like it never has before, went on a 40 mile cruise, I look down and I am doing almost 70, like it was on rails!!! I put in to account the big spindles (or its all in my head)
You might need a new shop, with an Old Timer....
