Good Long Weekend. I am looking at the 66 chassis manual, and it reads 4.46 - 4.49 from the bottom of the crankcase cover to the fan mounting surface of the blower bearing. That IS just short of 1 1/2 if I am reading it right. Right? Tom Wright St.Catharines www.vaxxine.com/tomspage 66 Corsa 140 Corsa Ontario CORSA
