Flywheel Casting Numbers

[Malitude]

Happy Easter!

Well, I have gone through the car to chack all of the numbers. Everything is numbers matching. I don't have any info on flywheels so I can't check these numbers. I have 2 flywheels and was wondering if anybody could tell me what they are for?

Casting number 3789738 date code B179 (Feb 17/69)

Casting number 3791021 date code C49 (Mar 04/69)

The car was ordered in Feb '69 and the original owner took delivery of it in April '69. Pretty much everything was casted in March. I did receive a 283 that was in the car which is now removed. Which flywheel is for this motor? The 3791021 casting has been balanced and is much thicker than the other.

Also, is there casting numbers on starters? If I give you guys the number off of the starter, could you check that as well?


Thanks in advance!
