I thought the CS130 was similiar to original Alt, but I noticed the center-center distance on the CS to be 6.1" and the orginal to be 6.6", Alan Grove said the 89 Chev truck 1 ton has the correct clocking and hole spacing. Would this Alt be electricaly the same as the 1436-5-11 Olds unit?

Just bought the 1352-6-3 for 89 chev truck 1 ton with 454 and it has the same hole spacing as the original setup. I think this one might be the hotter ticket???????
