i will just follow the steps of adjustment and its a 1951 chevy 3100. just want to know why they would want it setup upwards. usually to set up i've always full strided it linkage off then installed linkage the install linkage wiper off of glass and the tested to make sure the swipe was correct and then put on glass and adjust as nessasary. but then again thats usually on modern rigs. and idiots makin 6 figures dont know how to fix anything and engineers never fix (and they figure everything out when its new and ez to fix), work as a mechanic for a livin n see how off they are.
