I blew an alternator (driver side) and it was changed at one point with a caddy si27 ...i called my parts guy and told him i need a 27si for a 75 caddy ... he said a 22si would go in place of the 27si ... he sends me a 22si 160 amp... ok now i get it and the bolt holes are larger and the spread on the bottom is 4" too wide and the shaft is larger for the pulley i tell him and he sends me a 27si 160 amp .. buts the same exact as the 22si .... now i see on here guys are using the 22si and the large 27si , these look line the ones on my mack... question is how did you guys get it to fit?
