Per the '69 FSMBeing that this car has the HP axle package, what amperage should the alternator be?
Hmmmm, I have a line on a pair that has a casting date of 4-18-69 on the left & no casting date on the right. My engine build date is 4-25.
Alternator date codes are (week - year). Looking at the picture posted it appears to be 3 - 68, or third week of 1968. This would be extremely early for a May 1969 built car. Even if the date is 3 - 69, it is still early but at least in the ballpark. Can you see any of the pinwheel date codes on the alternator. There will be one on the front and one on the back.
Would the HP axle package qualify to be heavy duty of standard with all of the big blocks?
I see the car was delivered to Roseville C/P in Michigan. Would be interesting to know how & when the car made it to Massachusetts. Did the second owner acquire the car in Michigan? Did you purchase the car in Mass?
