anyone (Rick) have measurements on the smaller/early double sheave puley? Rick, does the pulley you made match the early short pump? If so, the measurements are in the PDF you mde at the posted link above right?
if my math is right (and your PDF is right):
1.025" from the face of the pulley to groove #1 and 1.725" to groove #2
Just got an email from a guy selling a pulley for a 69-70 I200. Says the groove measurements are 1" and 1 5/8". Without a micrometer, I'd say that sounds about right, no?
