1 3/8 sounds about right. Rather than pass the rod through the lever and double nut it I like to weld two parallel tabs on the lever end and use a Heim end in double shear. This will prevent bind in the linkage and side loading on the slave cylinder and also make clutch adjustments much easier.

It should be noted that the forward oil pressure tap was made a blind hole to mount the knock sensor on the EFI engines. I think it was tapped in a metric size too, making it problematic to drill it out for a pressure gauge fitting .
