Do you know if a clutch from a 4 prong pulley/hub is the same?
The parts book initially shows only one clutch and one field coil for '73 v/8 equipped cars. If memory serves me correctly, the 4 prong hub super-ceded the 3 prong unit and was a bolt on, but I am not sure. Parts book shows #3502327 super-ceded by #3502746 but it does not specify as to if the newer unit is a 3 or 4 prong.
