Starter solenoid lever -- retaining pin, or bolt ??

[jeffschevelle]

On the pin (or bolt) that holds the solenoid lever in the drive end of the starter, does anyone know when Delco Remy switched from using a bolt (with a lock washer and thin jamb nut) to using a pin (with a small retaining clip)?

I have verified that 1965 big block starters used the bolt and not the pin.  But I need to know for a 67 (May of 67 dated starter).   I have seen 67 big block starters both ways.  The 67 Chevrolet Chassis Overhaul Manual references a bolt and nut in the disassembly / assembly instructions.  But I suppose that could have been a failure to update the manual after changing to the pin, if a pin is in fact correct.

Any help would be appreciated!

If you're talking about #2,3 and 4.  #2 says shift lever bolt and #3 says lock washer and nut.  #4 says pin.  This is the 68 Overhaul book.

Thanks.  I did also verify on several original late 67 cars that the bolt, lock washer, and thin nut are correct.
