Has anyone replaced the wiper and turn signal stalk on the older model 4KCSQ, '86 with an upgraded stalk? I have to replace mine, and would LOVE to have the smother and more precise stalk from an 80 or 90 model, What chances that they should fit smoothly? ANy sort of modifications, or do you think that they should be generic and easily mount in place? Nick out '86 4KCSQ
