Voltage reg ID
 

Got these at the swap meet this weekend and need some ID help. The Neihoff has no numbers but I am guessing from the mounting holes it will work-at least that is what I am telling myself. The American Bosch is NOS and says it works with 6/12v systems. Does anyone have cross reference numbers for the Bosch?
The tune up kit is one I just had to get-it is from K-Mart and it fits my car!


Thanks,

Mike
